I'm red-green colorblind and the dots are extremely hard to see (at least for me). Any chance you might change them to be further apart in color, or use different colors? Blue and red, for instance, would not cause the same issue for me. Love the idea, though!

There exist colorblindness simulators. Vischeck is one, but it's apparently down.

This one acts on existing web pages: http://colorfilter.wickline.org/?a=1;r=www.google.com;l=0;j=...

ah, that's a great point! what're the best colors for indicating success and failure to red-green color blind folks?

Jenkins actually uses red/blue for this reason.

Any pair of colors except (red, green).
