GIMP :: Changing Semi-Monochrome Color
Jul 30, 2013
I am downloading semi-monochromatic picture files that I will be using for multiple applications. The image is originally semi-monochromatic with red and white being the only colors used. A complex image is created by adding more or less white to the red color. The image for each application I have in mind needs to be distinguished by the primary color of the image. I need to change this color first to green, then to orange, and so on. Is there a global command to change this one color?
I use the term semi-monochromatic because the pictures aren't actually black and white.

I want to remove only semi transparent pixels in a image. I want to keep others without changing them. How can i do that?
And is it possible to increase/decrease of all semi transparent pixels at one time?
For example: When i choose the increasing tranparency-alpha value at 20
if a pixels transparency is 120, it will be 140
if 75, it will be 95
if 255, keep it same
if 0, keep it same

My problem is that all of my dimensions and text have changed colour to white, with my by layer colour as an outline of the text, the arrows and lines still look correct however. I put the dimensions on a seperate layer and this seemed to happen after hiding this layer then later unhiding it. I have looked through the properties to change the colour unsuccessfully.
On another note, the monochrome print option does not work when creating a plot - it will still create it in colour. What can I do to sort these issues? It is fustrating as all I really need to do with this drawing is to export the it for a report and it looks messy!

I am using the Color Exchange feature in Gimp 2. I am trying to change a red background to black. The Color Exchange feature allows me to do that, however, it comes out with only part of the color changed and it all very blotchy.
Here is a screenshot of what happens after I select the red square and do a Color Exchange from red to black.

I have an image and all I want to do is change it to a different color. So if the image is mostly red, I want to shade it blue but still keep its quality, meaning the light-red pixels will turn light-blue, and the dark-red pixels will turn dark-blue.
I prefer an option that automatically changes all the colors for the entire image, but if there is a shader tool where I have to manually shade the image, that'll work too.
I input the image, then I went to Image > Mode > RGB, and from there I went to Colors > Colorize and used the sliders to change the image to the color I want.

Attempting to add text in Gimp 2.8.2. I can do everything I need (size, font, etc) except I can not get the color to change. When I change color, the text does turn a light grey, but it doesn't change color.
Here is a quick video I made with Jing showing my problem. You can see in the video that font selection changes and sizes changes, though.

I'd like to change the picture here:
[URL].........
So that the fur of the animal looks purple/mauve (in particular the gray part, it would be best if the white part didn't change).
I haven't found a way to do this, even approximately (which would be enough), in a textured surface. Methods I've seen changing the hue saturation seem to work when working with primary colors, but I can't get it to work with a gray color.

I am trying to plot a multi-colored layout in monochrome. I have gone through the page setup manager and set my style to monochrome. My prints come out in color. I have made my own propety and listed the print to be made in black only. Is there another setting that I need to setup differently to print in Black & White?

I can crop images, resize, and do a few other things but that is about the extent of my skills.
I am currently attempting to theme some images in an Android ROM but I'm not able to change the colors the way I want. Essentially I have a bunch of images with transparent backgrounds and white in the foreground. I simply want to swap out the white for another color (red, green, blue, whatever).
I have attached a sample image that I am working on. How on earth do I change the white to red (FF0000) for example? I tried using the select by color tool and clicking in the white area. Then I changed the foreground color to FF0000 and tried to paint into it. It doesn't seem to do anything but paint more white?
Some options were completely disabled for my image. For example, I went to Colors > Map and found that both Color Exchange and Rotate Colors are disabled. Why?
P.S. I have roughly 200 images that I need to perform this action on (and I may even do this with multiple colors -- create a blue set, a red set, etc.) so if there is some way to automate this process I would love to know. I'm a software developer and run Linux so I typically just write bash scripts for tedious tasks such as these. I know there is script-fu in gimp but I'm not familiar with it. Can I just call gimp within a bash loop and pass it some option to do this color change and save the new image for me?

That was one of my favorite effects in GIMP. Can do it just fine using Portable Gimp and 'use color from gradient'. But in GIMP 2.8.2 -- that's been taken away and we've been left with a confusing new Gradient system . Do NOT like it so far at all. Haven't figured out how to change the color of the sparks brush on it, let alone use it in any practical way.
Any way to be able to use this new version of the Gradient system and be able to change the color of the sparks brush?

[URL] ..... I have an image of a garage door on a white house. I need to generate a layer with a transparent background that when viewed over the original house turns the siding a different color say blue. The idea is that once I generate that layer I can then generate more layers like it to change the colors on the different parts of the house.
What would be the correct process in GIMP to accomplish this?

I have the following DDS file:
[URL]
I need to change that blue piece into dark green and the red into light green. Highlighting the section would be the obvious part, but when I paintbrush over it, it looks cartoonish. How can I keep it looking professional like that, whilst changing the color?

I've opened a gif file (web icon) which has shades of green. I want to use this on another site of ours which is similar but has shades of orange.
I use the dropper to select the color from a gif on the orange site - so the color is there in the color section box.
When I try to draw / fill on the green gif it ignores the orange color selected and uses a green from green gif. A lighter orange gives a lighter green.

I want to create a simple thin glowing red bar. I want the red to fade into black, pretty much exactly like what the glowing hot tool does with yellow/white.

I am trying to produce a new logo for our business that has a solid Blue cloud image on a transparent background. I need to add text over this but ideally it will show as white over the cloud background but blue when its over the transparent background.
Cant simply change the color of text as its a curved edge its going over. I assume I will need to do some form of punch out but not sure how to start this.

How to change the color of an icon (ex: from black to grey). My problem is that the end result is sometimes an icon that is partially transparent.
Here is what I am doing:
1) I open the image of which I want to change the color (black icon over transparent background)
2) Create a new layer and color this in white.
3) Merge the two layers
4) Create a new layer and color this with the color I want for my icon
5) Go to Colors -> Color to Alpha
6) Select the current color of the icon
7) Click Ok - Now icon color is the wanted color over a white background
8) Create a new layer and leave this transparent
9) Go to Colors -> Color to Alpha
10) Select the white color (current background color).
11) Click Ok - Now icon background is transparent, but icon color is also partially transparent.
Is there a way how I can change the color of an icon without getting the icon color transparent.

Here is the image I am working with.
I want to change the color to hex #00aced (0, 172, 237). I tried the colorfy, but the image comes out purple. Another way that has worked for me in the past, with white images, is by clicking on the channel dialog and dragging the red down. Clicking on the eye, next delete the original image and than add a new foreground color based on what color I selected from the palette. Of course this isn't working either since the image is so dark.
Now in channel mixer it could work if the RGB would go higher than 200, but since my blue is 237 this is where I am stuck. It has worked with other colors, as long as the RGB is less than 200. This is by selecting each output individually, for example, starting with red and entering a value in red and leaving green and blue at 0. Next selecting Green, entering a value in green and leaving red and blue at 0, and so on... Is there some type of mathematical solution for using the channel mixer, or simple yet, is there a way of making my image more white, without losing my shadows?

First time using GIMP. Following the directions here: [URL] ......
Using, "Color to Alpha," I tried to select the background of my .jpg image. The background is white, the picture (logo) portion is silver. Because of the closeness in color, when I select white, the software selects the entire image to become alpha (transparent).
When I select the color of the picture, silver, I am able to select just the logo portion. How can I take the logo portion, which is now converted to transparent, and give it a black or transparent background, and then return the logo back to its former color silver. The logo is perfect, it is just that I recently switched my site from a white header to a black header and the image has a white background, so that does not look good.

I want to use a monochrome image to create a (1/3 size) image with subpixel precision. For starters, a pure black&White clipart seems the easiest to do this with. But after toying around some I couldn't find or think of a proper way to do this.
Any method to convert greyscale-antialiased images to 1/3 sized subpixel antialiased ones?
- Scaled the vertical resolution to 1/3
- Created 3 copies offset by 0, 1 and 2 pixels respectively for use in the next step
- Masked out 2 in every 3 colums of pixels leaving R, G and B striped versions.
- Scaled striped component images to 1/3 horizontal resolution
(no interpolation, aligned so that it uses exacly the desired 1 in 3 colored pixels)
- Got stuck with three seperate R, G and B colored component images...
- Posted this question
Also, attached is an intermediate result of my efforts: the combination of the three striped R, G and B versions. Simply scaling the attached image unfortunately does not yield the desired (and expected) result.

I have an image that has corners with partially transparent pixels. I would like to make a mouse-over image of this with the same same dimensions, only a different color.
How can I color this image a different color and still have the partially transparent pixels around the edge. Obviously, I would like the semi-transparent pixels to be semi-transparent of the new color.
I'm still not allowed to use the link vb, but let's try this: ....

I have this Image: [URL]......
I am trying to keep the same image, but change the green hues to blue hues. I am fairly positive I can recreate the bottom part of the image (the rectangle with rounded edges aka a button), but I don't know how to add the top parts after that. Ideally I would just like to be able to change the greens to blues.

I'd like to find a "play" arrow/button (like on a media player), just a right arrow/button, somewhere and make it semi-transparent, and then place it on top of an existing image.

How do I get started creating semi-transparent text? What I am looking for is text which you can "see through" the reduced color (not text which is bordered and otherwise entirely "see through".
I have got as far as creating some text in a document.
I looked on Google and it pointed me at the Layers menu and then "opacity" which I don't have on 2.8, so I guessed "transparency". It won't let me "Add alpha channel" (which I thought I had to do) so I made the text colored (which I want in the end anyway) and tried "Color to Alpha" but no matter what I do I can't change it in any way with the dialog boxes that open. Which Means I may be chasing the wrong dialog box anyway, but although the labels are very good, the terminology means nothing to me.
In the end I want to be able to create a series of short phrases and have them overlapping in a text design, being able to "see through" the overlap to some degree.

On the image of the slider of my Homepage I want a semi transparent box to appear and then after a few seconds some text will appear on the semi transparent box. The text and the semi transparent text box are on different layers. I found a tutorial on a website and followed the instructions.I created a rectangle with the sizes I need and then:
Colour > Colours to Alpha > Left Click on the pop up box that appeared > Left Click on the Colour to Alpha Colour Picker > Click on the colour I want to make transparent > Export as .png
What I got is indeed a semi transparent foreground text box to place my text on but it is too dark (Pic.01). I would like it to be light semi transparent like in Pic.02 on the right(Avada 3: The Best Yet)
How do I change the transparency level / Opacity of the foreground text box? I changed the Opacity to 50% on my second try but I did not see any visible change.

We have experienced what we think is a bug in AutoCAD 2010's printing. We are running A2010 with Update 1 & 2 installed. Same issue on both x32 & x64 hardware.
Each project is setup with a title block xref'ed into the sheet (quite common method).
The Title Block xref generally has images loaded & therefore the image is a child to the sheet file when the TB is referenced in.
We have used this method for about 15 years across most versions of AutoCAD with no issues before now.
Now on AutoCAD 2010, when we print the sheet, the xref'ed TB images print black & white, rather than color. However if we use AutoCAD 2008 with same pagesetup/ctb/pc3 etc, we get the same print, but image is colour (as we would expect & want).
This leads us to think that there is some issue in AutoCAD 2010 with xref'ed images & how they are treated when plotting.
To complicate matters further, if we bind the title block, thus making the image embeded within the sheet, the images now print fine in full colour.
So, if a image is loaded via a xref'ed dwg, it plots in Black & White. If image is referenced into live sheet (not via xref), then it plots in color. All other xref'ed linework prints as expected (defined by ctb).
Is there any new variable which manages the colour printing of the image in A2010 which we are not aware of (that didnt exist in A2008)?

I'm trying to color correct some strands of fabric that are underneath a semi transparent fabric. I've been trying to paint the strands and use opacity etc...to properly color correct them, but are there any good tricks to keep the illusion of the transparency of the overlaying fabric?

I have spent hours trying to do this simple task in Gimp without luck. What I'm looking for is the border effect (without outer shadow) seen in the three embedded screenshots in this image: [URL]
In inkscape it's a matter of adding a square on top of the image with identical dimensions and making the stroke colour semitransparent and the fill colour completely transparent, but image quality suffers badly when exporting from svg to png or jpg again, and I'd prefer doing it in Gimp.
So, take image, say 100 by 100, add 1 pixel inner transparent border - how? I have seen this effect enough to suspect it's a filter option but haven't found anything in my filters.
