Why are no white or black colors in the rainbows?

White and black technically aren’t colors, they’re neutrals. Also, white is the combination of all the colors you listed, whereas black is the absence of color.

Or, white is the presence of ALL the colours in a spectrum of light. Black is the presence of all the colours if you mix them up as in paint.

Red, Orange, Yellow, Green, Blue, Indigo, violet?
That’s all white.

Black is, but at night, so you don’t see it.

Black is what your eye perceives when there is no light, RGB=(0,0,0). White is the combination of all wavelengths, RGB = (255,255,255) There are other colors missing from the rainbow, like brown and pink, which are combinations of frequencies.

There are no rainbows at night @Patty_Melt.

Yes there are. They are black, and you cannot see them, because they are made with no sunlight.

Rainbows ARE sunlight, period. Without sunlight, you can not have rainbows. You can have drops of water in the air still, but they won’t form a rainbow. It’s not like the water droplets gather in a rainbow shape in the air. That’s not how it works.

Why aren’t there black rainbows? Isn’t that discrimination?

^^^ Take it up with God.

On Saturn there are rainbows at night. They are called rings. Jupiter, Uranus, and Neptune have them, too, but they are too thin to be much more than a faint trail. And none of the Gas Giants or Ice Giants have a very solid surface, so you can only see them for like a second. Then you die.

It is still reflected sunlight, no matter what or where it is.

Aurora borealis

The aurora arboreal is created by a different event. I’m guessing it’s a type of radiation. Source

Again, those aren’t rainbows. They’re better than rainbows! I would love to see them sometime.
