I needed xterm colors for Spaceship 😎 but then it got out of hand.

lib.rs:

Query GitHub's Linguist library for colors for programming languages.

$ linguist-termcolor for rust

You can query with language names or file extensions.

xterm colors and color distances

For finding the nearest xterm colors, a --colors/-c option is available for specifying the color model or color space in which to calculate color differences using color_art::distance_with.

The default is RGB, which may not actually yield the best result in terms of human perception. For finding colors that "look" the closest, CIELAB is a reasonable choice; use it with -c lab. See ColorSpace for available choices.

For example, here are the different results for "python" using RGB, CMYK, and CIELAB, respectively.

$ linguist-termcolor -c rgb for python
 rgb #3572a5 xterm 61 python

$ linguist-termcolor -c cmyk for python
 rgb #3572a5 xterm 67 python

$ linguist-termcolor -c lab for python
 rgb #3572a5 xterm 24 python
