The arguments to that UIColor method should be in the range of 0 to 1. Divide each RGB value by 255 to get them into that range.


This is more of a PSA than anything (because I've seen more than a fair share of devs slap themselves on the head here too): Always ensure your using floating point division if your going to do this. That means always dividing by 255.0. I've seen too many people asking "why do I always get black" and pointed out "because you forgot the .0" :).

Well, I guess that explains that. I finally just gave up and did the math myself.

Good tip, thanks!
