This is good to use:

cell.textColor = UIColorFromRGB(0x333333);

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

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!

What I've always wondered in this particular context of our color
component specifications
ranging from 0.0 to 1.0 is why the System RGB color chooser displays
the component
values in the range 0 to 255? You'd think by now there'd be a
'Developer Friendly'
version of the chooser . . .
