Instead of colorized keywords, this contribution has *colorized variables and
functions* using the [rainbow identifiers][rainbow-identifiers] mode. Each
variable and function has a unique color associated to it.
The `saturation` and `lightness` of identifier colors can be adjusted with the
commands:
Key Binding | Description
--------------|------------------------------------------------------------
`<SPC> c s` | initiate change `saturation` mini-mode
`<SPC> c l` | initiate change `lightness` mini-mode
`+` | increase the `saturation` or `lightness`
`-` | decrease the `saturation` or `lightness`
`=` | reset the `saturation` or `lightness`
Any other key | leave the change mini-mode
