UIColor takes RGB values as a float between 0.0 and 1.0. To get that from a value between 0 and 255, you need to divide by 255.

[myLabel setTextColor:[UIColor colorWithRed:0/255.0 green:78/255.0 blue:255/255.0 alpha:1.0]];

You may want to write a category method that does this for you, or even a simple preprocessor macro.
