[Lel4_user] Color alternatives for Display in lel4

[jekarkka at mappi.helsinki.fi]

In my desktop "Applications - System Settings - Display" there are only
three possibilities to select colors. Of these, the alternative "256 colors"
is the only one which the graphics of my (modelling) program accepts. The
colors are not, however, quite acceptable.
Is there a way to create other alternatives besides these three " 256..
Thousands ... Millions of colors" to try to improve the colors in my program?
