Thanks logn. Much appreciated. Just to clarify a couple of points if you don't mind: "(although I can still tell it's a 5)" - that is - on the original? or only the python version? If you are able to see (almost) all numbers on the original, then perhaps your colour-blindness is not as strong? or the test isn't great to start with?? "However, I believe if given this test, my answers on the Ruby version would only deviate from the original...". Deviate meaning you won't be able to tell the difference? Would it be possible to contact you via email/skype to follow-up on this if necessary?

>"(although I can still tell it's a 5)" - that is - on the original? or only the python version? That's regarding the original. The numbers I see in the original (left->right, top->bottom) are: 12, 8, 6, 29, 57, 5, 3, 15, 74. Is that what you see? They're designed so colorblind people see different numbers sometimes. If that's exactly what you see then the test is either flawed or it's not inclusive of all the frames which test this colorblindness. I have severe color-blindness and take these at the eye-doc regularly. I also read the original color-blindness book in biology class once which is how I know my type. >"However, I believe if given this test, my answers on the Ruby version would only deviate from the original...". Deviate meaning you won't be able to tell the difference? Deviate in that on the Ruby version my answers might be: 12, 8, 6, 29, 57, _3_, _8_, _17_, _71_ Feel free to email me: pleasedofeelfreetosendmespam@gmail.com ... yes that's my email :)

Also, for reference, all the samples here: http://www.toledo-bend.com/colorblind/Ishihara.asp http://www.toledo-bend.com/colorblind/Ishihara.asp Except for the top-left 25, they're all spots for me. The 56 in the middle-right is maybe perceptible to me, but barely.

  Thanks again. That's cool. I'll try to pass those tests through the algorithm (both python and ruby) and share the results somewhere - hopefully it will be a better test case then. > If that's exactly what you see then the test is either flawed or it's not inclusive of all the frames which test this colorblindness Yes - that's what I see, so maybe these samples weren't the best to start with. I took them straight off http://daltonize.appspot.com/ http://daltonize.appspot.com/ so assumed they are a good starting point...
