I’m having a braindead moment…Someone has asked me to etch a Union Jack flag on a piece of edge lit cast acrylic. Fine…but how can I differentiate between the red and the blue as the laser only etches white on acrylic? I need a lie down LOL

Well I can only help with 2 colors EU flag blue with yellow stars. Simply stack layers of acrylic on top of each other with one color LED per layer ;-))
