The first 4 canvases copy https://p5js.org/reference/#/p5/colorMode examples. The 5th canvas is based on https://editor.p5js.org/mhf273/sketches/HJnkSK1jb but smaller. It's colors are random.
The last canvas was abstracted from https://p5js.org/reference/#/p5/blue and similar pages for green, red, brightness, hue, saturation, and lerp.
The p5js source file: colorTest.pjs.
