Maybe I'm going to split hairs here, but: yes, it makes a huge difference in terms of usability, but no in terms of accessibility. The information *is* provided in a format that you can use and understand even if colours are completely disabled or the difference between them is inperceptible. It does draw on a classic green=go, red=stop metaphor. Now, if that table relied solely on colour, it would obviously be another matter. -- Patrick H.
