The above two can be installed as backgrounds.
Colors that I have found to be safe to use with this tradition are as follows (all are Netscape-safe colors as well):
00FFCC
663300
990099
CC3300
66FF00
00FF66
3300CC
CC00FF
FF0066
FF0000
0066CC
Example pages follow, although these graphics and colors could probably be pretty well used in whatever combination you wanted to.
Set 1.
Set 2.
Set 3.
