The function responsible is this one:

How to expose colors? Any examples in other WBs?
Do the colors need to be exposed or can they be assigned by accessing the theme? For example ThemeConfig.ErrorColorText

These functions may cause the same problem:

@obelisk79 what do you need to style color / how to use text color from the preferences?

Just use the same variables as the Python Editor/report view should do the trick. Plus it would make things generally more consistent across the application.

The CfdOF Wb already has this implemented, see https://github.com/jaheyns/CfdOF/blob/master/CfdOF/Solve/TaskPanelCfdSolverControl.py#L81 and https://github.com/jaheyns/CfdOF/blob/master/CfdOF/CfdTools.py#L370

I personally added bold to the time just to make it stand out when I'm benchmarking a model on different pieces of kit.

@FEA-eng would you like to try the following changes https://github.com/FreeCAD/FreeCAD/compare/main...Syres916:FreeCAD:FEM_TaskPanel_Colours?expand in order to give a very similar output to the CfdOF screenshot above?

@Syres916 I tested it, looks good.
