Here is one full lesson from the Test Image series, free.

Nuke's ColorWheel shows 16.7 million colors. It looks impossibly complex. Then you pull the gamma all the way down and the whole thing collapses to three colors: red, green, and blue.

That is the entire visible spectrum on your screen. Just three colors, in different amounts.

In this lesson I show you that collapse, then how to actually read what you're looking at, sampling a pixel, capturing its RGB values, and reading hue. One thing most people never notice: RGB runs 0 to 1, but hue runs 0 to 360. Small detail, and it clears up a lot of confusion later.

This is one lesson. The full Test Image series builds from here, all the way to a reusable tool you keep.
