Since today, one of the people I worked with, suddenly has a different color user badge than all other users:
He doesn't know why his color changed. Where/how can he/anybody change his own color?
Unless something has changed, I don't think you can change the default user badge colour.
If its annoying enough, the user can go in to the ID settings and just upload a picture, made to simulate the default user badge. That's what I did when my colour unceremoniously changed to the same colour as another user, which kept making us confused. Just found a random online image editor to do it even.
(I may have decided to go for a fancier font/background at that point :P)
Its a pain in the butt, but in my case at least the colour change was affecting workflow.
Never seen this before but It might be in the Trello profile settings
- Click on the profile circle in the top right corner and then "settings"
or perhaps the Atlassian ID settings
