Hi Guys, Just wanted to say thanks very much for this. It happens I was looking at creating my own theme as a way of learning more about Leo and was really struggling with the stylesheets myself. FWIW, the way I was going about this was first defining my full color palette in a section within myLeoSettings as my-magenta, my-red, my-orange, etc., then applying those colors to the various objects in the stylesheet. This makes it a bit easier to swap them in and out of the @settings section depending on the context I'm in without having to reassign the major styles. Another thing I often do is set magenta+1, magenta-1 for more/less emphasis that can be reversed for light/dark themes. I'll post a bit more once I get it updated for the newer standard.
