Hello @Christopher_Kidd, as Justin noted, we have made some changes to how we handle color schemes, and you’ve stumbled upon a bug where editing a color scheme doesn’t update the changes. I am working on a fix for this.
For now though, I have fixed this on your instance by renaming the color scheme (renaming bypasses the cache mechanism).
WIll update here when the update fix is included, thanks, and apologies for the inconvenience.
Update: this issue should now be fixed via this commit.
