Is anyone else here really bad at colour blind tests? I have perfect vision. I can easily tell the difference between the orange/brown and the green normally used on the tests, but I have real difficulty defining the shapes of the numbers. I'm also fairly crap at 'spot the difference' puzzles and 'find 7 lions' pictures though.
