it does affect the colorblindness, some of the letters or numbers are merged or extrememly deformed (not surprising with Evony) that no one will ever get it right, i could send you all the screenshots of the captcha i gets, about 1/4 of them are impossible to read due to only the merged characters, 1/2 times i get wrong is due to similaries in characters.The captcha we went with is not affected by colorblindness.
As Dawnseeker stated we can easily plug in other captchas if this one is broken. We looked at some other captchas we looked at are in theory harder to crack but are harder to answer quickly. This does not mean that we think the one we have is crackable easily, there is just one very very commonly used one out there that is known to be pretty much immune for cracking and is used all over the internet, it is just a little hard to read.
