Is it possible, or would it be possible, to force designs to use a limited number of colors. For instance, we have a laser engraver and we regularly customize tumblers. When this process is done, the laser engraver removes the powder coating on the tumbler and leaves the base material exposed. This is essentially a 1 color design. I would really appreciate being able to give our customers access to the design ideas but cannot force the final design to a single color.
