I just realized that SO possibly blocks out many potential Moderators from editing questions. Due to color blindness. 7 % of males are red-green color blind (source wikipedia).
I am not saying that I know what to do about it but it seems to me that this might be a fact worth pointing out. (Perhaps some optional way of changing css template for color blind people. Yes, really).
In my biology studies I learned that microarray literature** (articles) f.e. Nature journal has changed their color scheme for microarrays from
blue-yellow (sometimes blue-red). (No, I did not find a source to back this up, you have to take me on my word).
** Microarry. A common device to analyze gene expression (DNA, RNA).
Microarray from Nature journal.
Edit of question by me.
Probably hard to see for a color blind, huh? (Perhaps an extreme example but not too uncommon).
