Use, NAO!

I've been using triad schemes lately but I was just using a color wheel image that I opened in PS and selected with Eye Dropper, but woo now I can just use this :P Found it 'cuz I was flipping through Colorful images in Photobucket and there was a screenshot of this :love:

You can also go to "Color List" at the bottom and go to each color code for all the shades/hues of the selected colors *o*

Its so cool! You can go to Vision Simulation at top to see how you'd see those colors but you have vision issues like color blindness or something that 1% of men have, etc.
