ColorShades is designed to help you choose colors by looking at grids of related colors. You'll have to set the center color of a grid using the intuitive Hue-Saturation-Brightness model. Then you have to pick which two out of Hue, Saturation, and Brightness you want to vary across the grid, set the step sizes and the app fills in the grid.
You can drag a color chip from any of the color rectangles in the grid and drop it anywhere on any application or color well that accepts color drags.
