RE: Contrast issue

I would say it does not conform to WCAG 1.0 checkpoint 2.2 (at priority
3)- Ensure that foreground and background color combinations provide
sufficient contrast when viewed by someone having color deficits or when
viewed on a black and white screen.

I tested it (with the CCA 1.1
http://www.wat-c.org/tools/CCA/1.1/index.html) using the W3C suggested
algorithms for colour visibility and both the darkest and lightest parts
of the gradient provide poor colour visibility.

I think this is beyond the point, users should not need to turn their
style sheets or graphics off to compensate for poor contrast.
