was pondering this...

Surely it's more than 16.7 million? ;) lol

How can it be infinity? There are only a certain number of wavelengths between black and white, and only a certain number of combinations of wavelengths...

Or maybe I'm not looking at it right.

I don't think you are, it's continuous not descrete... unless there's some quantum think that describes a smallest possible change in wavelength.

Light is analog, so in theory the number is very large.

~380 nanometer wavelength to ~740 nanometers, and all numbers between.

And colors mixing.. such as 420 mixed with 500 mixed with 733

Color mixing duplicates the color of wavelengths. It's just two different ways to see the same exact color.
