Yes, might be a nice little CAD once all the bugs worked out, might just be a file handling thing.
Not sure why we really need a separate file for R, G, B for QB colors. That could be setup and SHARED in a SUB or FUNCTION with it's own DATA line or code them directly into an array, perhaps with help of little code snippet to write to clipboard. Make it easy to edit a color, I guess. Why not make 256 X 256 X 256 colors available with Color Picker?
Also one ini file might be nice too, it looks like there are at least 2 saving a single value. Maybe that's planning ahead with hopes of extending options in future.
