> [https://p5js.org/reference/#/p5/get](https://p5js.org/reference/#/p5/get) Returns an array of [R,G,B,A] values for any pixel get(x, y) [https://p5js.org/reference/#/p5/hue](https://p5js.org/reference/#/p5/hue) Extracts the hue value from a color or pixel array. Hue exists in both HSB and HSL. This function will return the HSB-normalized hue when supplied with an HSB color object (or when supplied with a pixel array while the color mode is HSB) I tested this and it works for H and B but did not seem to give correct value for S. A little exploration lead me to …
