The color codes on this page are sourced from Customer.io's publicly available brand guidelines, press kits, and official resources. We strive to keep them accurate and up to date.

Brand colors are typically trademarked as part of a company's visual identity. You can reference them for educational, editorial, or interoperability purposes. For commercial use in a way that implies endorsement or affiliation, check Customer.io's brand guidelines.

The primary Customer.io brand color is Firmament Blue (#0E363D). This is the first color listed in the brand palette and is typically the most recognizable.

HEX and RGB values render consistently in digital media (web, apps, screens). For print, convert to CMYK using the values on each color's detail page. Monitor calibration and color profiles can affect perception, so always proof on target devices.

Accessibility depends on how colors are paired. Click any color to see its WCAG contrast ratios against white and black. Use our Contrast Checker to test any two Customer.io colors together.

We periodically review and update brand color data. If Customer.io rebrands or publishes new guidelines, we update our records accordingly. If you spot an outdated color, feel free to let us know.
