Welcome Leon. I have colour vision deficiency ie "colour blindness" and as correctly stated above this means a Class 2 medical certificate restricted to daytime only.
If you are interested/worried about colour vision link below to a good thread in the medical forum. This is mostly people (including myself) trying to pass a lantern test in order to get a Class 1 medical. I've done loads of lantern tests and they're never moving lights as stated above. All info here you could want:
