About Trello Brand Colors

Trello's visual language grew from the practical need to keep boards, cards, labels, apps, documentation, and merchandise coherent. Its early guide expanded one official blue plus green, red, and yellow status colors into weighted scales, while preserving the card as a recognizable interface object. The goal was a bright, useful system rather than color applied as decoration.

Blue, white, and dark text represent the service at a high level but cannot replace current Atlassian tokens, Trello themes, board backgrounds, or label scales. Labels can and should have names, not only colors. Third-party apps must not modify the logo, use it as their own icon, or imply official affiliation.

This unaffiliated reference does not distribute Trello, Taco, or Atlassian assets, represent a Power-Up or partner, imply endorsement, or grant trademark permission.
