Color Oracle Review + The Economist’s Red-Green Fixation

Wednesday, January 27th, 2010

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.

No self-respecting programmer, UX practitioner, or web site designer should be without [Color Oracle]

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”:

By using shape to reinforce (overload) the color difference, green and red can still be used to take advantage of those hue’s strong cultural significance (green = go, red = stop). The Economist, on the other hand, persists in NOT using shape to amplify the color differences in their charts and maps. 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:

iPhone app: Subway Suffle for Color Blind (Kelso)

Friday, March 27th, 2009

Kudos to the developer of Subway Suffle, my new favorite iPhone game, for including a “Better for color blind” mode in their game! This mode shifts the greens to a darker value making them easier to distinguish from the brighter red (see my blog post on this topic). Simple and elegant application preference solution that makes both audiences happy. Thanks Frank and Kristin!
