This is a General Discussion about the trend and fashion of RGB anything as there are too many to list , it has nothing specifically to do with computer hardware or how LED technology works .
RGB sports shoes , watches , clothes , clocks , toys , drones , fish tanks , car & truck , table lamps and even RGB osram lighting at bars and restaurants to name a few.
