Hi, sorry about this. A couple things are likely happening.
1. Getting something other than dark-blue back from the API when you set.
This is a bug we will look into. Color names were recently changed. The old names should continue to work and be mapped on read / write. Looks like that is not happening here.
2. Not seeing the color in the web app
This is more nuanced but essentially also a bug we are working on urgently. When you set the color in the API today, you set it only for the API user. A change was made to the web app to show only a “global” color for all users and not just the logged in user. We are working on applying this same behavior to the API. After that, you should see the color along with all other users. A bit more on this.
Apologies for this. I’m making a note to follow up here once the fixes are released (expect the fix for 2 to come very soon).
