It's free – ColorSmart by BEHR Mobile Review

Since it's free, install it on your device, pick a color you like, and then go down to HD and look at a chip of that color you think will make life better. Barely in the same color family. What good are all those visualization features when you can't get close to the actual color? You'll probably delete the app after you see how far off it renders the colors.
