The "normal" color blindness is red-green, not blue-green. That would also explain why you could see the yellow shapes, but not the red ones in a green background or the green ones in a red background. The vast majority of color blind people are red-green color blind. My grandfather was red-green color blind, so I've studied up on it. Luckily, I don't have that problem.colchar wrote:
My colour vision is so bad that I think I am worse than the normal blue-green colour blindness.
Everyone can check out the links below and see how their colour vision is.

I have a TINY bit of trouble with blue, but that's because I have an eye condition. I have extra light rods, but fewer blue cones. My night vision is better than most people's, but I don't see blue QUITE as well as most, but I'm not color blind. It's more like I have trouble distinguishing between CLOSE shades of blue than that I can't see blue (don't worry, I CAN see the difference between Duke blue and Carolina blue. However, I have trouble seeing the difference between, say, Carolina blue and the blue on the old Houston Oiler jerseys.)
For the record, I saw on the plates in the second test: 2, 5, 42, 7, 29, 6, 57, and 10.
