UIColor colorWithRed:green:blue: always produces black

Question

I have come across many instances when I try to make custom color through code and the result is quite different from Photoshop, e.g

[UIColor colorWithRed:         


        

Answer 1

colorWithRed:green:blue:alpha , each parameter specified as a value from 0.0(MIN) to 1.0 (MAX)

[UIColor colorWithRed:(160/255.0f) green:(97/255.0f) blue:(5/255.0f) alpha:1];
