 For static colours, either set each colour separately (for example `--w-color-primary: #2E1F5E;`); or separately set [HSL](https://en.wikipedia.org/wiki/HSL_and_HSV) (`--w-color-primary-hue`, `--w-color-primary-saturation`, `--w-color-primary-lightness`) variables so all shades are customised at once. For example, setting `--w-color-secondary-hue: 180;` will customise all of the secondary shades at once.

 To quantify the emissions of a Wagtail website, we recommend three different approaches:
 
-- The [Sustainable Web Design](https://sustainablewebdesign.org/calculating-digital-emissions/) model, which uses page weight as a metric of energy efficiency, and page views as a metric of site utilisation. This model has clear [known limitations](https://www.fershad.com/writing/is-data-the-best-proxy-for-website-carbon-emissions/), but is nonetheless ideal to provide high-level figures for a wide range of websites or pages.
