I think this guide falls into the trap described in this article: https://refactoringui.com/previews/building-your-color-palette/ https://refactoringui.com/previews/building-your-color-palet... where the mathematical model gives us colors that we should believe are harmonious, but which actually lead to clashing primaries, and a chaotic-looking interface. The RefactoringUI book (from which the preview above is an extract) gives a much more useful model to work with, when creating a palette that helps the end-user by establishing a clear and harmonious hierarchy of visual information.
