Analyze Color Contrast
Color contrast analysis performs a detailed color contrast analysis of the page using the WCAG 2.0 algorithm for color contrast.
The purpose of this check is to ensure that the contrast of the text against the background is sufficient for someone with low vision to read. If the colors are too close in luminosity (brightness), FireEyes will flag this as an error.
FireEyes can analyze colors in the style sheets as well as in background images. Background images with many different values, such as busy photographs, may require manual analysis in addition to analysis by FireEyes.
Note: This algorithm is included in the "Now" analysis. You do not need to run the color contrast analyzer separately.
