It definitely does. While I like some color (monochrome themes aren’t my bag), a lot of themes are too much for me and distract me more than they help me. I’m definitely on the “less is more” end of the spectrum.

When you say “however, colors work magic for reading code for me”, do you mean having most text in the same color, say purple, or do you mean having a variety of colors? Because the article specifically complains that “everything is purple” in elixir-ts-mode instead of having a wider variety of color.
