Pygments (Python) is Hugo legacy and not recommended for general use as it's an external binary and not offset of Hugo itself. The old "pygments" names in config make me cringe a little though I still use them too.
Note I built the theme roller linked above for Pygments the first time around, and it like Hugo's boilerplate highlighting themes is backwards compatible under Chroma too.
Think of Atom One Chroma as a tool for designers who like to code and coders using color theory to plug in color swatches to achieve precise color control across their entire site.
