mapsam opened a new issue #7843: Colorblind friendly UI URL: https://github.com/apache/airflow/issues/7843 Hello! Thanks for all your work on Airflow :) ### Description Reds (failed) & greens (success) colors are not colorblind friendly. ### Use case / motivation As a deuteranope, when I view recently run dags, it's not clear which runs succeeded and which failed. To me, this is probably one of the most important features of the Airflow UI.  *You could convince me everything succeeded or failed in this screenshot.* ### Suggestions Totally understand that red/green are important for our common expectations of failure/success, so I'll just propose some other reds/greens that work for me, with the caveat that there are many more types of colorblindness than my own so it's worth getting a diverse set of opinions here. Something other than default `red` and `green` web colors will be tremendously helpful though! **`red` / `DarkSeaGreen`** - simple change, works well with the yellow "running" value  **[clrs.cc](http://clrs.cc/)** failed = `#FF4136`, success = `#2ECC40`, running = `#01FF70` - this comes with the bonus of being [A11Y compliant](http://clrs.cc/a11y/).  Happy to create more combinations, if helpful. Cheers!
