Themes

kx theme              # list the palettes, with a preview of each
kx theme dracula      # persist a choice
kx theme 3            # ...or pick it by number, like anything else

The choice is written to ~/.kx/config.toml, and KX_THEME overrides it for a single shell.

The palettes

Eleven palettes ship with kx: github-dark (the default), dracula, nord, gruvbox, solarized-dark, catppuccin-mocha, tokyo-night, rose-pine, mono, light, and plain.

The light palette is for light terminal backgrounds. The mono palette drops color but keeps bold and dim, for terminals or captures where hue is noise. The plain palette disables styling altogether, the same as --no-color.

A palette is a set of colors, not a background. On a terminal whose own background disagrees with the one a palette assumes, the palette will look wrong — that is the terminal and the palette disagreeing, not a bug in either. The light palette exists for exactly this reason.

One registry, three surfaces

The palettes are defined once, in the kx binary. Three things read them:

the terminal, for every command’s output
the HTML reports — kx diag --html and friends are drawn in the palette you have set, so kx theme nord restyles them too
this site, whose stylesheet is generated from the same registry

Which is why the picker in the navbar offers the same ten names kx theme prints. Pick one and the page follows, tab icon included.
