RGB LEDs emit light in three primary colours: Red, Green and Blue. The intensity of each colour in an RGB LED is controlled independently by multiple LED chips meaning different colours can be achieved. These colours include the secondary colours of yellow, cyan and magenta as well as a whole spectrum of other hues making these LEDs extremely versatile. RGB LEDs have many uses including decorative and ambient lighting in the office and home, theatre and concert lighting, automotive lighting and for eye catching displays and signage.
