thanks but can i use it with rgb colours or do i still have to use one of the default colours?

can i use this?:

Code:

[myButton setTitleColor:[UIColor colorWithRed:100.0 green:100.0 blue:100 alpha:1.0] forState: UIControlStateNormal];

thanks for the help bro.

Right idea. Check the docs on that method, though. Max is 1.0. Make sure you use floats for each value: 1.0 for blue.

never mind guys, i think i figured it out:
this:

Code:

[myButton setTitleColor:[UIColor colorWithRed:100.0 green:100.0 blue:100 alpha:1.0] forState: UIControlStateNormal];

should be this:

Code:

[myButton setTitleColor:[UIColor colorWithRed:100/255 green:100/255 blue:100/255 alpha:1.0] forState: UIControlStateNormal];

I have been trying to get the values for Bubblegum to work for a button. This code you posted should work but it doesn't react as expected to the value given for it on List of colors - Wikipedia, the free encyclopedia.

It just appears as white just wondering if you know off hand why it may not be working.
