Red vs. Green
This is from Microsoft Excel 2010.
And I have a confession to make: I can hardly tell Good from Bad… like 1% – 6% of all human males I have a slight defect of color vision. We are not a threat to society: we can tell apart the traffic light signals and other color-based discriminators used in machinery, weaponry etc.
So why don’t UI designers take us into consideration? I’m sure there is a ton of research on creating dichromacy-friendly color palettes.
The RGB values for Good are 198, 239, 206. For Bad: 255, 199, 206. Are you kidding? How can anyone tell these apart? Now let’s increase saturation (+40 in Photoshop):
Now I can clearly see the difference. Good RGB: 200, 255, 130. Bad RGB: 255, 199, 206. See, Bad wasn’t affected by the saturation boost. And Good became… greener and lighter.
… Lately I’m sooo disappointed by what Microsoft is doing in UI/UX. It’s cargo cult… Failed attempts to copy Apple… I’m so glad Steve Sinofsky is no longer there… I wanted to write a huge rant about Windows 8, but I don’t even know where to start.
