One next step is to discover a good color option for buttons and links (the actions). I take a slightly different approach here. Instead of going for AAA, I’m sounding for MA (a reasonable standard toward strive for) so that I cannot get a lightened colour to contrast from the static text and draw attention to important links. For these purposes, I'm testing white (#FFFFFF) in mix with various colors.  How darken script for readability? - Apple Community
