Model and Sheet Colors are different

I am running DraftSight version V1R5 under Linux Mint 16, 64bit, Cinnamon Desktop, Qt Cleanlooks theme.

My dimensions are on a layer of their own with the color set to No. 56 (RGB 127,127,0) Here is a screen shot of part of the Model space:

And here is the same part of the drawing in Sheet space:

Using a color picking app (gColor2) I can confirm that the Model space color is indeed 127,127,0

But the Sheet space color is 76,76,0 which is DraftSight color reference number 58.

If I choose a basic red color for dimensions then they appear as pure red (255,0,0) in both the model and sheet spaces.

What is going on?
