Lets see... Greens, oranges, and purples go together.
Yellows, reds, and blues go together.
Whites mute, blacks vividfy (I made that word up).
Pastels are for girls. Deep dark colors are for MEN. Greens are for spring, browns are for fall, white is winter, summers, we all just go swimming.
Now, everyone here will tell you... I don't know a thing about what I am talking about. They are right. I just pick colors I think go well together.
