Theme colors

The design system provides a flexible color palette that meets accessible color contrast requirements.

The palette is designed to support a range of distinct visual styles that continue to feel connected. The intent of the palette is to convey a warm and open American spirit, with bright saturated tints of blue, grounded in sophisticated deeper shades of cool blues and grays. These colors — combined with clear hierarchy, good information design, and ample white space — should leave users feeling welcomed and in good hands.

This is a simple, minimalist color palette. Shades of blue dominate, providing a neutral backdrop on which brighter shades, clean type treatment, and bright white content areas “pop” on the page.

Brand colors

Primary colors

This palette’s primary colors are blue, gray, and white. Blue is commonly associated with trust, confidence, and sincerity; it is also used to represent calmness and responsibility.


Secondary colors

These are accent colors to provide additional lightness and style to pages looking for a more modern flair. These colors should be used to highlight important features on a page, such as buttons, or for visual style elements, such as illustrations. They should be used sparingly and never draw the eye to more than one piece of information at a time.


Accent colors

Accent colors are used sparingly to support primary and secondary colors in designs and illustrations.

Background colors

These colors are used largely for background blocks and large content areas. When alternating between tones, be sure to use enough contrast between adjacent colors.


Status colors

These colors are used largely to indicate the status of something. Be cautious using these colors to signify something that may contradict what most people would expect the colors to be used for.

Accessibility considerations

Text contrast

WCAG 2.0+ AA requires a contrast ratio of a minimum of 4.5:1 for normal, or body, text. Large text is easier to read, so the contrast requirement is reduced to 3:1. WCAG defines large text as text that is 24px and larger or 18.5px and larger if it is bold.

Text over gradients and background images still need to meet contrast requirements.

Non-text contrast

Elements that are not text, but still important, including buttons, icons that convey information, data visualizations (charts and graphs), and form inputs need a contrast ratio of at least 3:1. Also included in this are states of elements such as the selected state of an element, expanded vs. collapsed, active vs. inactive, elements with keyboard focus, etc.

Easily test your color combinations

Note that the colors listed only display colors that are available but when you are pairing colors together, make sure the color contrast ratio is sufficient. Here are three tools we suggest for testing color contrast:
