Calcite Colors

saturated color wheel

The calcite-colors repository provides Esri's official color palette including documentation, reference files, and helpers in multiple file formats.

Color reference files

The following links are to download the .ase swatch for use in Adobe products such as Adobe Photoshop and Adobe Illustrator. Additionally, there is a PDF download of the visual reference color palette.

Sass Variables

A Sass variables file can be found in the root directory colors.scss. This is the main source to consume the color variables.

Sass Theme Mixins

A pair of Sass mixins are available which will return the two themes as CSS custom properties. In this way, you can add css vars to your app if need be:

@import "@esri/calcite-colors/dist/colors.scss";

:root {
  @include calcite-theme-light();

[theme="dark"] {
  @include calcite-theme-dark();

These colors are then accessible with the var syntax:

.my-element {
  border-color: var(--calcite-ui-blue-1);

ES6 Export

In a modern javascript environment you can import the colors via ES6 import:

import { colors } from "@esri/calcite-colors/dist/colors";

console.log(colors["ui-blue"]); // => "#007ac2"

UI Colors

In both the Sass and JSON file are UI Color variables. These variables should be the standard usage of color for most applications. They'll serve as an easy way for users to grab the main usage colors so colors stay consistent across applications. They include both Light and Dark theme variables. Dark theme variables have -dark appended. Additionally, both light and dark include variables for hover and pressed states ($ui-blue-2, $ui-red-3).

Chart Colors

Colors for charts are included as well. These can be used to import colors for charting libraries.
