Hello all, I really like the default GitHub Dark color scheme as it's quite visually pleasing for math equations, the slightly dimmed white text being reminiscent of smooth Hagoromo chalk on blackboards. However, I'm struggling to find a good set of syntax highlighting colors that also have the same pastel palette reminiscent of colored chalk on blackboard while remaining readable. Common chalk colors are yellow, orange, pink, green, blue, and purple, but there are also other shades offered in specifically in the Hagoromo Fulltouch lineup. Does anyone have good suggestions of the color set to use, or perhaps know of an off-the-shelf theme that isn't too cartoonishly blackbord-like?
