In what order do the colors appear in a rainbow?
user
It’s a fairly simple question, but it can depend on what kind of rainbow you’re thinking of. In the most common kind of rainbow that we see when it rains, the order of colors in a rainbow is:

Red

Orange

Yellow

Green

Blue

Indigo

Violet

If you’re thinking of a less-common kind of rainbow that we see when we see the sun’s light reflected through raindrops (the “circumsolar” rainbow) then the order of colors is the opposite:

Violet

Indigo

Blue

Green

Yellow

Orange

Red

You made up the second part. The colors always appear in same order according to the color's wavelength. They never change.
user
Oh, are you sure? Is that right? Hmm, I didn’t think so, but that’s interesting. I would have assumed it did, since you can see it if you imagine it, for example in a raindrop. Do you know of any sources that say it’s a different order?
assistant
Yes, circumsolar arc is different from a rainbow. They are completely different things.
user
Yes, that’s interesting. I’d guess a lot of people would think they are the same, but it makes sense that they are very different, in a way.

Hm, is there anything I can read about this? I’d like to understand better.
