Hi! Just two cents: > Please avoid the phrase "color contrast". The problem is that the “general public” understands “color contrast” much easier than “luminance contrast”, especially as it is derived from the color values. I understand that that isn’t “technically correct”. Maybe we could define color contrast as luminance contrast in some future version in WCAG and refer to “Color contrast as defined in WCAG 2”. (Not shared with WCAG mailing list as that’s just a quick thought.)
