This file contains paragraphs with “automatic” foreground colour on a variety of background colours and the contrast ratios for these colour combinations. The contrast ratio calculation is based on the contrast algorithm from the W3C's Web Content Accessibility Guidelines (WCAG) 2.0: http://www.w3.org/TR/WCAG20/#contrast-ratiodef. You can check the contrast ratio using a tool such as The Paciello Group's Contrast Analyser (for Windows and Mac): http://www.paciellogroup.com/resources/contrastAnalyser. I propose a threshold for switching to a white background when the contrast ratio according to WCAG 2.0 is lower than 4,5 to 1 (4,5:1). -- You are receiving this mail because: You are on the CC list for the bug.
