So did I... yet I still failed the colour vision test for the medical. Unfortunately the UK (and JAA) still persist with colour vision testing which is utterly irrelevant to the actual flying of an aircraft. Stupid dot plates like that (administered IN TOTAL BREACH OF THE MANUFACTURERS INSTRUCTIONS), and 40yr-old murky flashing pin-prick disco-lights are all you'll get in JAA-land.
There's a tremendous amount of head-in-rectum attitude to the subject in Europe. The FAA do proper real-world testing and have done for donkeys years, "can you see that light? what colour is it? fine...".
