Simple extension allowing the selected label colors of cards in Trello to fill the entire card. Settings allow either combing colors of multiple labels by simple rgb base value average or pick the color of the first label. - Fixed issue with changed classes - Reduced CPU load by only updating the DOM when there are changes - Fixed some style issues and added an option button to select between 'merge' and 'use first label color'-mode to the top left menu. - Should play more nicely with stickers now. If not - let me know.

Seems to have stopped working again. I can't find anything similar and it's messing up my whole system. Would really appreciate an update for this! It's a really useful extension.

[Not sure where to contact the developer, so I'm doing it here] NO LONGER SEEMS TO WORK. Seems to work on the first "pass" but then fails on every pass after that. Possibly conflicting with Trello's card covers feature? (This new feature still isn't as nice as the chrome extension and I wish the extension still worked) There's a weird bug with the "Merge labels" etc selector: Also, feature request, I would like to be able to choose specific labels (per board, of course) that the color-er should use (instead of just "First label").

Risk impact

Card Colors for Trello requires some risky permissions and may not be safe to use. Exercise caution when installing this extension. Review carefully before installing.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Card Colors for Trello has earned a good reputation and can be trusted.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.
