Can you or Alex expand on this? I'd especially want to know if this was true on non-white backgrounds.

  Yes its especially true for non-white backgrounds. It all has to do with contrast. With black on white we have 100% contrast, if we use dark gray on light gray the contrast becomes say 70%. The lighter the contrast the easier it is on the eyes. Here's a quick example of what it looks like. http://cl.ly/1p103C2z1N220L1W213l http://cl.ly/1p103C2z1N220L1W213l

      Interesting link, but you're missing the point. The website even misses on their points. Most of the bad examples fit under an acceptable contrast ratio, by the standards given in their research, and even their good examples are not pure #000 or #fff. The w3c states that a minimum level of 3:1 works for people with 20/20 vision and 7:1 achieves the Triple-A standard. To show you what it looks like. http://cl.ly/0J3Q210X142x1h2m1G2v http://cl.ly/0J3Q210X142x1h2m1G2v for reference http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contr... and contrast tool http://www.snook.ca/technical/colour_contrast/colour.html http://www.snook.ca/technical/colour_contrast/colour.html
