Or perhaps you did, but that was the effect you wanted?
Have you ever designed a web site (personal or professional) that had lots of red? Or lots of green? Or (worse) both?
I’m not saying “worse” because red and green are the by-now-ubiquitous Christmas colors, at least in North America. Rather, it’s because of the 1/5 of the human population who is colourblind. Red-green colorblindness is the most common, but that doesn’t just mean that protanopes can’t see only those two colors. They may also have trouble distinguishing between yellow and brown. Blues may appear nearly black. There’s a neat tool that you can either use online or download to your desktop. It will check your web pages or other images, and show you how they would appear to a person with vision difficulties like macular degeneration, retinitis pigmentosa, corneal haze, or true colorblindness.
