Light Colour
LEDs produce light in a limited spectral range. This has enormous advantages for color applications compared to other bulbs, where color filters filter out large parts of the produced light.
Using RGB LEDs, we can produce almost all colors to the eye, including white light. However, white light-emitting diodes are, for reasons of cost, based on a blue chip that is coated with a phosphor. The phosphor converts the blue light into white light.
