The arguments to that UIColor method should be in the range of 0 to

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" :).

Good tip, thanks!
