Details

The GOV.UK design system includes a colour palette, these can be accessed via the govuk_colours vector, it includes both Sass variable colour names (e.g. govuk-text-colour) as well as the named colour palette.

The GOV.UK colour scheme was not designed with data visualisation in mind. The govuk_palette function provides an opinionated selection of GOV.UK colours for use in charts (e.g. via ggplot2::scale_fill_manual()).

The categorical palette (the default) provides an opinonated set of six GOV.UK colours for use in categorical/qualitative palettes.

The blues palette orders the GOV.UK colour palettes blues from dark to light and can be used for sequential colour palettes. Alternatively you can supply a name from the govuk_colours vector to generate the end-points for a sequential palette using that colour (where the lightest colour is roughly a third lighter than the input colour).

There are also four opinionated palettes for use in a divergent scale, these all use an off-white (the mid-colour between GOV.UK light grey and white)

• blrd which use GOV.UK blue and GOV.UK red as its end-points

• blrd_dark which uses GOV.UK dark blue as its blue end-point and a darker red of the same hue as GOV.UK red as its red end-point

• blyl which uses GOV.UK blue and GOV.UK yellow as its end-points

• putq which uses GOV.UK purple and GOV.UK turquoise as its end-points

The categorical and divergent palettes have been checked for general support for users with colour blindness.

Value

A set of hexadecimal colours
