Getting started

First review the key terms used and then proceed to the colors section.

Color

Displays the color name. The first part indicates the main functionality or its service family. The last part indicates the darkness or lightness of the color; 130 is typically the darkest and 5 is the lightest.

Value

Displays the HEX and the RGB color values.

Utility class

Displays the CSS class you may use to reference this color.
This feature is currently only available if your site is hosted on the Publications Office portal.

The first class gs-u-color-name-XX is for font-color, and the second class gs-u-bg-color-name-XX is for background-color.

CSS variable

Insert our CSS variables into your custom classes or inline styles to use our global definitions.
This feature is currently only available if your site is hosted on the Publications Office portal.

For example, we use the CSS variable --gs-base-color-lavender-110 below to make the word COLOR lavender.

<span style="color: var(--gs-base-color-lavender-110);">COLOR</span>
