Keyboard key colour change

[Ofnuts]

If you want to replace a saturated color use Colors>Map>Rotate colors. Pitfall, in the to circle, the range shouldbe wide enough to include colors of the reflections (in particular on the side of the return key, which would other wise keep a green tint. No need for a selection here but if there are other keys of similar color you may want to exclude them with a selection (while keeping the reflections of the key you are changing).
