1. Background Color
Use pure-white
as the background color for most pages. White backgrounds help the page content stand out and provides a minimal aesthetic for the UI. ³

2. Card Layout Background Color
For card layouts, alabaster-grey
should be used to help the cards stand out and create a sense of separation between them without over powering the UI. ³

3. Icon Color
Avoid using non-neutral icon colors as they can distract users from the page content or confuse the meaning of the UI. Our default icon color is graphite-grey
. ⁴

4. Text Color
Use the text colors to establish content hierarchy.¹ Use lighter color text for less important information and darker color text for more important information.

4. Border Color
Dark borders can overwhelm the interface. Subtle lines provide definition without being overbearing. ² Our default border color is mercury-grey
and should be used for most borders.
