Meeee tooooo!
However, thinking on it...... I have two ways I cam do this.
First the most difficult.Paint the light color. Mask, but I would have to cut the mask into postage stamp size sections with the cloud openings to paint green. This would mean I would have to cover the openings of the postage stamp size cracks, too fiddly.
Second, the easiest...... would be to paint it overall green! Then place the cloud part of the mask, simple, then spray the Light color.
Easy peasy................
