To be fair, we don't actually know this canonically.

I failed to make the scope of my "canonically" comment clear. I meant it's canonically speculated that Klingons can't see all of purple that we do, but I personally observe that otherwise their vision seems to be similar to ours. I agree that we don't have any real information on the details.
