Which among the following are primary colors?

  • A.Red, green, blue
  • B.Yellow, violet, blue
  • C.Blue, yellow, green
  • D.Red, magenta, yellow

Answer: A

The primary colours of light are red, green and blue.

They match the three types of cone in the retina, and mixing them additively in the right proportions produces any colour, including white. Pigments mix subtractively, and their primaries are cyan, magenta and yellow.
