I hate when I know enough to know I don't know emough

I need to set the font and background colors of different items on a form and I've dug around a bit and found some color names, clRed, clBlue, etc but I need things like Lite Blue, Lite Green, etc. Is there a list somewhere of default colors available or will I have to make them up and set constants myself. If the latter is true the next question is is there a tutorial somewhere on defining colors?
Thanks
Bill
