This week's MIX12 challenge at SCS is about using either predominately hot or cold colors and adding a pop of color from the opposite side of the color wheel. If you are like me and never had the opportunity to learn about the color wheel in this manner this is a great starting point with brief description, video as well as great examples in the SCS gallery.
