The
background is actually a small piece that looks like this:
It is then duplicated up and down the screen for the full-page effect.
By using the smaller piece, the art loads much, much faster - about
400,000 times faster, since it's a very tiny 1Kb file instead of a huge
file all across the page (400Kb+). Note the bottom matches the top so it
appears seamless when put together.
The colors you mention above (purple, fuschia, orange, golden yellow,
bright green, brilliant blue) need to have exact color matches (see Web
Safe Colors link at the top of the page). Computers and colors are very
unforgiving and do not depend on the various human interpretations of
"brilliant blue" for example. Brilliant blue to one person is
not brilliant blue at all to someone else - so we use the numbers, just
like printers use the Pantone color system.
I could spend days trying to get the colors you want from a word
description and still not succeed. So please use the color chart and
the numbers that match the colors.
