Just about every color method in iPhone OS takes a value from 0.0–1.0, not 0.0–255.0. To get the color you're looking at in The GIMP, divide each of your values by 256; thus, the correct UIColor method call would be [UIColor colorWithRed:0.0 green:0.0625 blue:0.2344 alpha:1.0].

So in otherwords, RTFM. Your answer is correct, thanks for not just writing, "see Apple documentation".

Just a note for why you get the result you saw in case has similiar problems and comes across this question... colorWithRed:green:blue:alpha: chops values to the range 0..1, so 16.0 and 60.0 both become 1.0 making [UIColor colorWithRed:0.0 green:1.0 blue:1.0 alpha:1.0] which you'll notice gives the same result.
