Addition of light

Addition of light is the mixing of primary colour lights to produce secondary colour lights

Primary colour	Primary Colour	= Secondary Colour
Red	Blue	Magenta
Green	Red	Yellow
Blue	Green	Cyan
	Red + Blue + Green = White

On this page we've discussed adding red, green and blue light in equal intensities. What happens if they are added in unequal intensities? For instance, suppose you are on the stage lighting team for your school's theatre. Your task is to control the red, green and blue stage lights to produce various color effects for the upcoming show. Use the Color Addition widget below to adjust the strength of the red, green and blue lights relative to full strength. A 1.00 indcates that the light is on at full strength; a 0.00 means the light is off. (All numbers should range from 0.00 to 1.00.) Once adjusted, click the Mix 'Em Up button to find out the result of mixing red, green, and blue components at various strengths
