Understanding the math behind blend modes

This started as a REPL session to try to understand why our Goodbeast.com colors look so much better when a friendly designer used them than when I did (other than his exceptional sense of color). I realized that he was "overlaying" them on top of themselves, effectively increasing both brightness and saturation.

This all came together as a shader, forked to start and mostly credited. https://www.shadertoy.com/view/DtKyRc

The overlay function in the javascript version can be thought of more as an "S curve" in a design program - it increases

/******

	Amplify's DataStore is useful, but it is very, very immature and has some
	incredibly naive implementation choices.  One of those is that it will
	perform synchronization on the first call to query, regardless of a call
	to start.

	This is an issue, because most non-trivial applications will require a
	login so that the app can load appropriate content for the user in question.
