WHITE LIGHT IS CREATED WHEN THE PRIMARY LIGHT COLOURS OF RED, GREEN AND BLUE LIGHT BEAMS ADD TOGETHER.

THE SECONDARY LIGHT COLOURS ARE CYAN, MAGENTA AND YELLOW LIGHT BEAMS.

A MIXTURE OF DIFFERENT AMOUNT OF COLOURS WILL CREATE THE OTHER COLOURS

FOR EXAMPLE 1 PART RED AND 2 PARTS BLUE WILL MAKE A VIOLET LIGHT.

IF YOU USE 1 PART RED AND 4 PARTS BLUE IT WILL BE PURPLE

A WHITE SURFACE WILL BE SEEN WHEN WHITE LIGHT (A MIXTURE OF COLOURS OF RED, GREEN AND BLUE LIGHT BEAMS) REFLECTS TO THE EYE.

A MIXTURE OF DIFFERENT AMOUNT OF COLOURED LIGHT BEAMS REFLECTING FROM DIFFERENT COLOURED SURFACES WILL BE SEEN AS DIFFERNET COLOURS

SEE A SHORT VIDEO BELOW FOR MORE INFORMATION.

YOU 'SEE' A COLOUR WHEN ALL THE OTHER WAVELENGTHS OF COLOUR ARE ABSORBED INTO A SURFACE, AND ONE IS REFLECTED TO YOUR EYE.

IN THE BACK OF THE EYE ARE RODS (WHICH 'SEE' BLACK AND WHITE) AND CONES (WHICH 'SEE' COLOURS)

THEY THEN SEND CHEMICALS TO THE BRAIN WHICH THEN COMPUTES WHAT IS BEING SEEN.

SOMETIMES THERE IS AN OVERLOAD IN THE SYSTEM AND THE BRAIN COMPENSATES.

SEE THE VIDEO AT THE BOTTOM OF THIS PAGE WHICH EXPLAINS AFTER IMAGES IN MORE DETAIL.

THE PRIMARY LIGHT COLOURS ARE RED GREEN AND BLUE   (RGB)

THE SECONDARY LIGHT COLOURS ARE

CYAN (GREEN AND BLUE LIGHT ADDED)

MAGENTA (RED AND BLUE LIGHT ADDED TOGETHER)

YELLOW (GREEN AND RED LIGHT ADDED TOGETHER)

THESE CAN BE MADE BY ADDING THE LIGHT BEAMS TOGETHER, OR WHITE LIGHT GOING THROUGH FILTERS (EG GLASS) OF BOTH COLOURS
