AutoCAD .NET :: Assign Colors To Dimension Lines / Arrowheads / Text

I just created a dimension style called "Test" and I am now attempting to use its DIMCLRD and DIMCLRT properties without success.

DIMCLRD is supposed to assign a color to dimension lines and arrowheads. How to use this property to assign, say, color index 140?

AS well, DIMCLRT is supposed to assign a color to dimension text. A code snippet on what I am attempting to accomplish is posted below: 

Dim tblRec As DimStyleTableRecord = New DimStyleTableRecord()

tblRec.Name = "Test"
tblRec.Dimasz = 0.08    ' Sets the arrowhead size
tblRec.Dimclrd = ???     ' Here is where I am attempting to assign a color to dimension lines on this dimstyle
tblRec.Dimclrd = ???     ' Here is where I am attempting to assign a color to dimension text on this dimstyle
