That's about right.

Quite so. The red one is somewhat dimmer than the green, but much
brighter than the blue. (This is of course because sunlight is
yellow...)

But note that powderblue is actually nearly white (176 224 230)... so
this doesn't apply so much. If anything, the higher blue intensity
merely starts to compensate for the fact that we can't see it so
brightly after all :)


Oh, and this doesn't to everyone by a *long* chalk :) A damn interesting

90% of any UI design course is crud, I have learned :( so *much* of UI
design is `what you are used to works'. Humans can adapt to nearly
anything: even JCL.
