About Duolingo Brand Colors

Duolingo’s own identity guide names #58CC02 Feather Green as the core color associated with the brand and #1CB0F6 Macaw as one of its bright secondary colors. The system grows from Duo, the green owl mascot, but it is broader than one character: Eel gray supports typography, Snow white supplies the primary background, and a larger cast and palette keep lessons expressive.

The three colors listed here capture Feather Green, Macaw, and Snow, yet they are only a subset of the documented system. Duolingo assigns different colors to typography, backgrounds, characters, and states, and warns that Duo’s green can vibrate against some backgrounds. Interface use therefore needs semantic roles and contrast tests, not a blanket substitution of green for every action.

This independent reference does not reproduce Duo, Duolingo logos, character artwork, or downloadable assets; it does not imply endorsement or replace the current official identity rules.
