Excuse me, but I resemble that remark. Please don't shout about it, my employer doesn't yet know! I get round it with an iPhone app called ColourBlind.
TBH, I thought I'd have a lot of trouble, but I rarely do. Even Cat5/6 isn't a problem when you learn which pairs are opposite each other inside the outer. The ones I find easiest are the multi-core black ones with numbers printed on the cores

I did have an entertaining morning with a 20 core (10 twisted pairs) that needed to be identified by colour, but be methodical and it's all OK. Oh, and when I say 'morning' yes, it was a whole morning, I had 80 terminations - two ends and a JB in the middle with 40! I have no idea what was connected to the JB and at the end, I just terminated in the panels as instructed with cable IDs and ferrules. The PLC and the equipment were someone else's problem - though I have a feeling I'll be revisiting them at some point.
Certain colour deficiencies do not preclude becoming an electrician.
