It often happens that it’s not at handcolor leds. But you can find a way out of any situation. For example, make colored LEDs from white LEDs.
We need: sandpaper (preferably the smallest), markers of the desired color, white LEDs.
Emery processed LED, so that it becomes matte. This is done so that the paint penetrates deeper into the surface and does not wear out.
Paint with a marker.
Voila! Here is our color LED.
Good luck
