Hi
Since for some experiences in moose we needed more named colors I started to gather together some old extensions and I cleaned the implementation. Now we have emacs colors and XKCD i.e around 1600 named colors.

I would really like to see how we can model the notion of color palettes.
Hi, Material Design have some recommandations that are nice. They recommande to have two colors for an application: - A primary color - An accent color The primary color is the main color of the application and the accent color is to make some highlights (links, important buttons...) For each color they defined scales. Each color have a code (50, 100, 200, 300, 400, 500, 600, 700, 800, 900). The base code is 500. If you need something "less important", with less contrast, you takes a lower code. For more contrast, you takes a higher code. See here: https://www.materialui.co/colors Also they have recommendation for text color. Dependently of the background color they define if the text should be white or black. (This is defined by the luminescence of the color in Pharo). Also, they define different text color if you have a primary text or a secondary text.
