I don't find that they add anything. I feel like they make it harder for me to do a coherent read of the screen, to suck in all the text & process it. I have my own mental algorithms to pick out relevant things, and having a bunch of glaringly contrasting blocks of color glaring out of the terminal at me just makes it harder to slurp in the screen. I don't want that segmentation. It's awful.

And the color themes for the terminal are godawful. No matter how you spin 16 colors, how solarized or other, everyone is kind of chained more or less to that attrocious 16 color pallet, which is always going to be way way higher contrast or low-fi than something like a vim theme that can pick some complementary colors to work with.

Colors feel like my terminal punching me in the face. No thanks.

Also have you ever logged into ubuntu? Holy shit colors were a TERRIBLE idea.
