I am posting this because it’s a page that I’ve been spending a bit of time with today. I often have to look up what Apple calls many of its system colors – beyond the simple primary colors. The documentation that Apple provides does a really good job of showing you the various colors, their uses and how they are affected by light or dark mode. Needless to say, this is a necessary page for any Apple interface designers.
