Hi folks, reading a message on webaccessibile@itlists.org mailing list, I found this: Andrea Martinez wrote that he tested the WCAG conformance logos with http://www.juicystudio.com/services/colourcontrast.asp, and the response is "strange": - Red text "AAA" Background: #ffce63 Foreground: #8C0000 The difference in brightness between the two colours is sufficient. The threshold is 125, and the result of the foreground and background colours is 166. The difference in colour between the two colours is not sufficient. The threshold is 500, and the result of the foreground and background colours is 420. Whilst the colour difference doesn't comply with the W3C specified range, it does comply with the range used by Hewlett Packard. Hewlett Packard recommends a colour difference limit of 400. - Grey Text "WCAG 1.0" Background: #ffce63 Foreground: #39394A The difference in brightness between the two colours is sufficient. The threshold is 125, and the result of the foreground and background colours is 149. The difference in colour between the two colours is not sufficient. The threshold is 500, and the result of the foreground and background colours is 372. Maybe this is the same for all W3C logos, isn't it? Should we do something?
