In my Dyno I have some groups. Yay! 
But a week later I realise I’ve used the wrong colour. Boo. 
With the OOTB colours I can change them. But I can’t seem to do this with my Monocle colours.
Could this feature be added pls @john_pierson
EDIT: Well… I can click on the group and click the colour in custom grouping window… But it then changes another group 
Yes. That’s a long-standing bug that I haven’t quite figured out yet. 
Let me see what I can do.
But I want it nooooowwww 
For now, I think you could transform the colors by editing the group colors in a text editor. Once you get that working in a manual method you can try automating the transform in a file using a DYN, and then bulk transform many files via DYN…
Ah, it’s not a bulk thing I was talking about (this time).
It’s when I’ve put something in a “Input” group but it should be in a “Output” group kinda thing.
A few groups at most… I can un-group and re-do it but it’s annoying.
I believe i have fixed it.
Check out the GIF below. I am going to push this to the Package Manager shortly.
Whoooo!!! Yeah
Just for R23 or will it work in older issues?
It should work on Revit 2021-2023
Whooo!! Thank you
