Card Colors for Trello

CRX id


Description from extension meta

Takes card label colors, either merge them or pick the first and add them to the entire card.

Image from store Card Colors for Trello
Description from store 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.

  • (2022-09-21) Nenemaria: 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.
  • (2020-07-09) Derek Antrican: [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? https://blog.trello.com/card-covers-and-colors (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: https://i.imgur.com/DVZGHFt.png 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").
  • (2020-07-08) Mel McMurrin: All the cards turn white about a second or two after opening. Left to right. Developer has no contact info. Would be 5 stars bt no longer works. Merge button work around I read about does not help. HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  • (2020-07-03) Sebastian Schenck (smirc): I used this for a very long time. Perfect! but since month do not work anymore. Trello build up, the backround is colurfull. Perfect, but then a kind of reload happends and all cards are white again. :-(
  • (2020-06-30) Michael: same problem ... card colours are no longer displayed! Please fix it.
  • (2020-04-16) Марк Дерманов (dermanov_ru): Очень полезное дополнение! Уже очень давно пользуюсь. На днях стало глючить и у карточек больше не закрашивается фон(
  • (2020-04-16) lars r-s: Great extension to Trello, just of late, it is doing the following, you quickly see the colour on the card then it goes white, not sure if this is due to chrome so uninstalled chrome and reinstalled it, but it still does it. Is there a fix for this.
  • (2020-04-16) Dan Bergin-Holly: Can't see any developer support page, so I'm posting here. Really like this extension, but it seems to have broken recently :( Would love a fix if possible!
  • (2020-04-16) Saga Sundelin: It's good, but before, all my cards were colored. Now it's only the cards with 2 or more tags.
  • (2020-04-16) Nazar Kulchytskyi: Not sure what changed but it stopped working since last few days. It just removes tags from card and don't add background to it.
  • (2020-04-15) Aaron “A.J.” Toews: Same as other users, worked fine til a week ago. Now colors dissapear, though labels remain. I have re-installed with same issues. If I refresh, I get color back if I click on the "merge colors" bar at the top. But as soon as I move a card, it turns white and then the "merge colors" bar vanishes. Any ideas?
  • (2020-04-15) not working any more
  • (2020-04-14) alex gerdner: Love this extension, stopped working last week - I emailed the developer and they're working on it. Very responsive and helpful
  • (2020-04-14) Lee Mole: Card Colors Just Stopped Working Hi my card colours disappeared since last week. I rebooted, uninstalled and installed to no joy. Whats going on and how do i fix this great extension? Lee
  • (2020-04-13) John Worrall: I loved this extension for years, but after a system update last night, it has stopped working.
  • (2020-04-13) Альберт Мурзабаев: It was working fine until last week. Now it is working after refreshing the page for 1 second but then every card turns white(
  • (2020-04-12) sma: Same here. Please fix it. :)
  • (2020-04-10) Matt Fleming: As of April 10, 2020, the app works periodically. Sometimes it will color the tabs, then the next moment it disappears complete (not even a small colored bar on the card), then if you refresh the page it sometimes comes back. App used to work all the time, just not sure if there was some update that broke everything?
  • (2020-04-10) Tomer Barkan: I used to love it but it stopped working. Now all cards appear white and I can't even see the label stripes, had to turn it off. I hope this gets an update to fix the issues but considering the last one was in 2017, I realize it may not... I'll change my recommendation if it's fixed.
  • (2020-04-10) Andrzej Pieńkowski: Used to be great, except the double button bug. But today just stopped working. Trello must have changed CSS classes. :( I really hope the developer will fix that.
  • (2020-04-10) Julian Mason: For me this is an absolutely essential extension, but it stopped working a few days ago. I've tried uninstalling, reinstalling, refreshing etc. but cannot get it too work. Is it perhaps in conflict with a Chrome update?
  • (2020-04-10) Juan Martín Sanguinetti: Is it just me or it stopped working? Now the cards remain colourless and do not show even default colour labels. I turn it off and on and this app is causing it.
  • (2020-04-09) Mark G: A great extension and use it all the time, but I have a question. I have used this for a while and then recently, one Trello board will not accept the coloring. The Trello board loads and the colors appear and then they disappear and stay gone. Any thoughts why? Thanks.
  • (2020-04-09) Rogério Bettoni: Here is the website of support team - I think if a lot of people talk to them, they will get it fixed. https://support.trustpilot.com/hc/en-us
  • (2020-04-09) Karessa Manning: I love this feature and have used it for a long time, however yesterday it stopped working for the first time. The colors will show up momentarily, but then all the cards turn white. The cards don't even show the label with the default trello settings unless I remove the extension. I have tried reinstalling chrome and the removing and readding the extension, but it has not fixed the issue. I do not know how to contact the developer to let them know so I am posting it here. I really love this feature! Please fix this issue. Thanks!
  • (2020-04-09) Andreea Visanoiu: Love this extension, I've been using it for the last year. It seems not to be working as of today, anybody knows what the issue is? Chrome update / Trello UI update? I tried all of the extensions possible, this is the only one that does the work.
  • (2020-04-09) Kenny Baker: This worked until today, I don't know how to reach the developer, but whatever Trello is doing with Butler just busted this and I'm super sad. Please Patch a Fix!
  • (2020-04-08) Centro de Asistencia Traveler Assistance: It worked great but all of a sudden stopped working.
  • (2020-04-08) Skaine12: Essa extensão é excelente, mas parou de funcionar de repente, o que pode ser? Poderiam liberar para outros navegadores como o Novo Edge e firefox? Obrigado!!
  • (2020-04-08) Markus Knoke: It has stopped working, unfortunately
  • (2020-04-08) Shan Brf: Does anybody else have a bug that when trello loads, the plugin loads properly but after a few seconds all of the tiles lose their color? Started happening today after a chrome update to 81.0.4044.92
  • (2020-04-07) Olivia Dekok: Can't figure out how to contact the developer. Love this extension but for some reason it has stopped working for me. I've been using it for several months.
  • (2020-04-06) Nick Hall: was 5 star until it broke today it loads for a split second then another script or something says NOPE aaaagh ruined my day it even worked earlier today, darn trello must've done something
  • (2020-01-30) Eleanor Lim: I'd really like the option to have labels AND card colours on the board. Some cards only need a label and I'd prefer them not to be totally coloured. Especially with the bigger cards - that's a lot of green/red/purple... Apart from that, pretty easy to use once you figure it out, and very eye catching.
  • (2019-07-31) Peter Cameron-Burnett: This is a brilliant extension - we use it for our AgileOS system for things like recurring items on our sprint boards. It saves space as well as making the board visually easier to use.
  • (2019-03-19) Yalcin Yilmaz: I like it. Options to use "first or merge" is fine for me. One annoying bug though.. This selector for "first or merge" appears 3 times at the top of the page, as other users have also noted: https://i.imgur.com/DVZGHFt.png Takes up so much space on some boards...
  • (2019-02-28) Очень нужное и хорошее дополнение. Спасибо!
  • (2019-02-07) No instructions provided, so spent 15 minutes trying to figure out how it worked and never could. I'll check back later and adjust my rating when instructions are provided.
  • (2018-11-22) Quiksilver Hu: Installed the plug-in, it displays in the right corner, but I can not find, how to use it. :(
  • (2018-11-18) D: Like: that it colors the full card, which is very useful. Don't like: the mixing of the colors. Not helpful. If a card has three labels, say green for marketing, red for its project, and blue for being an 80/20 task, what would be most helpful for me would be to have the option to have the entire card blue, with a red and green label showing at the top the way Trello does it. That way I can move the blue task over to the Action board, and have it labeled also as coming from X project, and a marketing task. As it stands, the color will simply blend into a mushy green color, which tells me nothing about the labels applied. And isn't nearly as pretty as the blue. Overall, good product as long as you stick to one label color. If they fix this issue,then my rating would be 5 stars.
  • (2018-10-14) Mohammed Yasser Moghrabiah: awsome
  • (2018-10-01) stefan ketola: Unless I'm missing something it seems to offer no control at all. I just changes the colour of some cards chosen at random to a colour of it's own choosing. I was looking to colour code cards to aid in organisation - this doesn't help :(
  • (2018-08-01) Priscilla Frye: I like it now after figuring out why I could not get the color to cover the whole front of the card. I had also installed the Trello Features app extension. It has a feature similar to Card Colors & I guess there was a conflict.
  • (2018-06-06) Roman Dobusch: Excelent extension. Have been using it for past year. But past few days I have been experiencing same bug as Derek making it problematic to use...
  • (2018-05-08) José Renner: Seria legal se quando o cartão tivesse mais de uma etiqueta, ao invés de combinar a cor ele dividisse o cartão com as cores. 50% Cor A 50% Cor B Ainda assim, aplicação fantástica!
  • (2018-04-06) Gus Fahrendorf: Sure don't work no more - Out you go!
  • (2018-02-23) Gabba Productions: I have no idea how this app works. I downloaded it and it attached to my Chrome bar where it happily sits doing nothing. There are no changes to my Trello app and nothing in this app that seems to link the two. I shall soon uninstall it and resort to crayon and paper. Seems faster.
  • (2018-01-02) Dennis Rasmussen: Nice add-on for Trello. Is it possible to change the "first" label on a card? Otherwise it seems a bit irrelevant to add more than one label to a card.
  • (2017-08-07) Romina Mazzali: It started working after restarting my notebook
  • (2017-07-22) Keith Adams: Decent app. Would like the option to select the card colour based on a label that is already on the card

  • (2015-03-23, v: Sebastian Schenck (smirc): Card with two or more colors
    If you have a card with two or more labels, only one color is used for the background. A quick win is in my opinion, to show the old labels and use one color for the background.
