Thank you for your help on our XD Community. I tried replicating the issue on both Windows and macOS 12.6 versions; unfortunately, I do not have 12.5 currently, and I was able to use the color picker on both windows and macOS 12.6.
Do you have any other machine on which you can test this? I will also check on 12.5.1 once I'll have the machine. Also, if you can share any specific workflow where it's not working?
