Hisham Abboud over at the Curious Chap blog promo’d Color Oracle, the software that the talented Bernhard Jenny programmed (with my sometimes helpful nagging) for simulating color blindness.

Nice endorsement, thanks! Hisham uses an Apple iPhone website chart to emphasize his point: “My first brush with what one can do for color blind persons was a 2007 post by Greg Raiz. Greg described how Apple was using red and green circles (same shape) to illustrate which stores had iPhone availability, and how they later switched to using different shapes”:

Not only does this make it hard to read on my evening subway commute, they are completely illegible for color blind readers. The January 16th, 2010 edition has a particularly egregious example:
