I use 4 checker tools (WAVE for Firefox & Chrome, Paciello desktop
checker, and the WebAIM web page) in different ways. I also make sure
designers have these tools and are checking their work.
I couldn¹t test your page, was blocked from our proxy server, so I can¹t
identify what might be happening in your situation.
Not sure how you are using the Chrome WAVE plugin, which I LOVE BTW, so
here¹s what I do. Select ³Contrast² from the choices at the top of the
sidebar to reveal the Details interface. Click on the icons that display
to locate errors. I am not sure why all of the icons don¹t display on the
page being tested (layers or animation perhaps?) but many of them do.
Guessing it¹s reading the CSS perhaps?
In general I trust my eye and then test using Paciello¹s dropper tool most
of the time. Or to be 100% sure, if I don¹t have a palette or a designer
to ask, I grab the colors from the CSS (if they are presented as hex
values and not percentages) using a code inspector and then plug them into
the WebAIM Color Contrast Checker.
Hope this helps.
Best,
