I have created a DrawArea widget under motif and have colored the foreground of this region using Xcolor "DeepSkyBlue".
The problem comes when I want to select the foreground color to use with rubberbanding. ie. a rectangle. What is the method fo selecting a foreground (x) color that when used with Xor, displays the desired color (y)?
Note: If the DrawArea is XFillRectangle with "DeepSkyBlue" and I draw a line with logical function GXxor and foreground color = "White", the color of the line drawn is "DeepSkyBlue".
