"ROYGBIV" as taught in school. But if you're wanting accuracy, I'd claim some number near infinity.

Can you give an example of a number near infinity?

220 (C-class) - close to Infinity

350 (SLK) - greater than Infinity

1 rainbow = infinity - 1

Yeah, something like that. The Red + Violet thing reduces it from infinity, in my opinion, to something near infinity. Maybe it's INF-1, or even less, but not infinity.

When I was a kid we always said "red, orange, yellow, green, blue, purple", but of course there are a lot of transitional shades in between. I'd count indigo as one of those, since it's not a very well-known color by name. In fact, I've never heard of it at all outside the context of rainbows. Nothing is ever described as being indigo in color. If you're going to list indigo, you may as well include spring green, cyan, periwinkle, aqua, teal, fuschia, and chartreuse while we're at it.

Apart from the eponymous SGI workstation of blessed memory.

What exactly does that have to do with Perl?

Nothing. It's just my signature. If you don't want to see people's signatures on Perlmonks, you can put something like this in your stylesheet settings:

```div.pmsig { display: none; }

Nothing is ever described as being indigo in color.

The Dinosaur Whiteboard strip 569 gives a counterexample.

Chemists Ferdinand Reich and Hieronymous Richter named indium after its indigo spectral lines.
Fine. Nothing is ever described as being indigo in color, except that particular section of the visible spectrum.
