Illustrator :: Choosing RGB Color (swatches And Sliders Remain In CMYK)

I'm making a simple template to laser cut. The laser cutter acts as a printer and you choose the power, speed, etc. for each color that is in the document. I only want to cut, so I only have RGB red lines at 0.001 pt thickness. Or at least that was the plan. One of the shapes in my template has come out a different red (the swatches were CMYK despite the document colour mode being RGB). I would now like to select all the paths in the document and make them all RGB red. However, when I open the color panel from the dock the sliders are CMYK, again this is despite the document color mode being RGB:
 
How do I change all the paths to be RGB red?How do I stop Illustrator offering me CMYK options and swatches and offering RGB instead?
