Im not much of a programmer and never worked on Android apps, but my guess is, you need to 1, get the current X and Y of the cursor(I know its touch screen, but its still going to be an x and y hit when its touched somewhere) and then get the pixel color in hex value. Maybe searching for how to capture the X and Y position will lead to results for how to then get the pixel color.

These might help you -

Just had another thought, might be easier, is have the app load it in a html frame, and use javascript to get the mouse position and the color of the pixels under it. I think there are javascript color wheel examples that can use images as input for the color selection.
