SASS

Chi defines colors with Sass language variables.

$colorscheme: (
  grey: (
    100: #242526,
    90: #313336,
    80: #3f4145,
    70: #53565a,
    60: #72767a,
    50: #8e9399,
    40: #acb0b5,
    30: #d0d4d9,
    20: #edf0f2,
    10: #f8f9f9,
  )
);

A utility function has been created to reference them.

set-color($scheme, $tone)

To use it, add chi through npm and import the variables and mixins sass files.

@import '@centurylink/chi/src/chi/_variables';
@import '@centurylink/chi/src/chi/_mixins';

.example {

}
