Hi, I know this isn't really an issue with MUI rather an issue with the original program.
The author of the original software is non-contactable so I have tried this instead.
Changing the colour using the colour wheel or RGB settings does not set the correct colour using MUI 5.0.
In the below example, changing the colour from RGB $00A000 (med dark green) to #FF00FF (light pink)

The colour is changed to a light green.
Doesn't matter what colour I choose it is always the same light green colour.

End result...

This problem does not occur if I use the older MUI 3.8.
Any ideas how to fix this problem?
I am not a programmer, so a simple fix would be good.
Thank you...
