Description
Colors entire Trello card backgrounds based on label color. Supports light and dark mode. Trello Card Colors is a lightweight Chrome extension that fills the entire background of each Trello card with its label color — automatically, with no manual setup required. Trello's built-in "Cover" feature lets you color cards, but requires setting each card individually. Several older extensions automated this, but broke after Atlassian updated Trello's interface in 2024–2025. Trello Card Colors is built for Trello's current DOM structure and is actively maintained. Features: • Automatically colors card backgrounds based on the first label assigned to each card • Supports all 30 Trello label colors, including light and dark variants • Full dark mode support — colors automatically shift to their darker variants for readable contrast • Reacts in real time to board changes, drag & drop, and theme switching • No configuration needed — install and reload Trello • No data collection, no external requests, no permissions beyond trello.com
