  Use this code (below) that initializes the variables,displays them in the text fields,and then sets the color well accordingly.This is a useful little app for OpenGL programmers-sice RGB values are calculated from 0 to 1 like OpenGL,you can experiment with color values without having to continually type them in and recompile a full application.

  {
  redValue = 1.0;
  blueValue = 1.0;
  greenValue = 1.0;
  alphaValue = 1.0;
  
  [redField setFloatValue:redValue];
  [greenField setFloatValue:greenValue];
  [blueField setFloatValue:blueValue];
  [alphaField setFloatValue:alphaValue];
  
  [self updateColor];
