I have just released a new application, Clean Color Wheel 2.0. With it you can easily view relationships between colors (analogous, triad, complementary), on a sleek interface. This app is an overhaul of a previous application I had published, Clean Color Wheel. Although the original was kind of a turd, I believe the new version runs smoothly and could be very useful for design purposes. Please download/rate on the Android Market, and post any suggestions you have here.
