Why is there no color pink in the rainbow?

Question

Asking on behalf of a 7 year old child.

Answer 1

Pink is a bright color of the red hue.
It wouldn't show because the sun's spectrum shows only Red, orange, Yellow, green, blue, Indigo, & Purple.
Pink is kind of a bright and less saturated hue of red.

Answer 2

Because the way a prism works (and water droplets function like that causing rainbows), light is refracted/reflected into the seven rainbow colors: Violet, indigo, blue, green, yellow, orange, red. Technically, there are several shades of these colors, and since they are not discreet, I am sure pink is somewhere between orange and red.

Answer 3

Pink is not really a color but an optical illusion of mixed colors

Answer 4

because each of the colours in the rainbow is monochromatic, which is to say they each is comprised of a single distinct frequency, each different from each other, much like the pure single tone that you get from a tuning fork.
pink however is polychromatic, it is a mixture of light of many different frequencies, much like the sound you would hear from a dozen or more different tuning forks each of a different frequency but all singing together to make a new sound that is different from that made when played one at a time.

Answer 5

Pink does not make up the color spectrum of light.

Answer 6

there is no pink because the colors of the rainbow are in order of the color wheel and pinkis not one of them

Answer 7

Ther's no brown or cream or black either!
