Putting white or black in between adds another anchor point.

And looking more around examples of blue and orange tie dye, most aren't really gradients overall, they have big splotches of solid color with small gaps or overlaps in between, and at least half the time the gaps and overlaps don't even have a gradient inside them.

> We may have to agree to disagree that tie-dye isn't a quintessential example of a gradient. Would you argue that rainbows aren't either?

Hmm. How about this. I would say a rainbow is not a gradient between two colors, and the color space discussion is about a gradient between two colors. The exact border of "quintessential" is not something I really want to spend too much time on.

In my mind a gradient is simply a smooth transition between colors with no universally agreed upon definition. The choice of specific curve through colorspace is rather arbitrary. It seems perfectly reasonable to want to include grey and perfectly reasonable to want to avoid it.
