Hi!

I love that colorls supports and comes with themes for dark/light modes, if set by the user per-usage. I noticed an issue from some time ago #165, in which a commenter suggested using ANSI colors. The way I use my terminal mostly these days is with the integrated term in VSCode, which I've set to switch theme based on my daily OS (mac/windows) dark/light cycle. Unfortunately, I don't know how to auto set colorls to use the appropriate theme based on light/dark mode.

Would it possible to either bake-in such functionality to be configured as the user wishes, or does anyone have any easy scripts or aliases or something that can take of this?

The easiest option for me or anyone else really would be to support ANSI color names within the color.yaml files, and let the terminal themes take care of the rest

Contributor guide

Research direction
Investigate how to detect OS level dark/light mode in Ruby (e.g., using default preferences files or system commands like `defaults read g AppleInterfaceStyle` on macOS). Look into the existing theme loading mechanism in colorls' codebase to understand how to dynamically switch themes based on detection.
