If I understand the report correctly, the problem is not with gnuplot's
display of colors. It is instead reporting a problem with the Windows
clipboard operation.

A bit of Googling suggests that the problem may be because we switched from
using CreatePenIndirect() to using ExtCreatePen().  Apparently some versions
of Windows have trouble with ExtCreatePen and the clipboard.
But I did not find a definitive statement or a recommended alternative.

Understood.  But it would be useful to know if you can replicate
the problem on your Windows machine, and whether switching that
one call back to CreatePenIndirect() fixes it.  (I realize that would
re-introduce other problems, but at least we'd confirm what the issue is).
