> try to remember what color your color theme uses for class names?

While I overall agree with the point of this post and the post being cited, I disagree with the premise that you need to be able to actively recall facts like this. The theme I personally use is quite toned down, but it does use different colors for variables, keywords, arguments, type names, and a few other classes of tokens. I don’t consciously think “hmm, what color is an argument” to look for those in my code - I just see them, have learned them over the years, and it’s muscle memory at this point, and helps me read the code. Just like I can’t remember the code to my apartment building, yet I type it in multiple times every day.
