Colour blindness on the Web
A good discussion about color blindness by a color blind user ...
"Colour blindness has crept back on to the agenda recently. Joe Clark recently pointed to SmartColor: Disambiguation Framework for the Colorblind, a proposed algorithm for converting colours in a document (or more likely an image) into colours that a colour blind person can distinguish. Also doing the rounds is Etre’s Colour Blindness Simulator which enables you upload images to see how they look to some colour blind users.
The thing is, colour blindness on the Web isn’t a big deal. You do have to bear it mind (as I will show later on), but there is no need to let it dominate any design decisions. I can say that confidently as someone who has been ‘diagnosed’ with strong protanomaly, a form of red-green colour blindness. In over ten years of using the Web I can list the problematic websites I have encountered on one hand.
And it’s not just me. My brother is a long-time Web user and through the miracle of genetics, he has the same form a colour blindness as I do. My brother couldn’t think of an occasion where a website caused him problems because of his colour blindness. And neither could a well known web designer with deuteranopia, another form of red-green colour blindness." continued ... (Via clagnut)
