Thank you very much. It works now. I don't actually add any new face if
they exist is because the were added by packages.

About the user friendly interface you mentioned previously.

I may be wrong, but I think it doesn't need a new face and custom
option, we just need to use the same whitespace-tab face for
tab-mark. It will be more coherent because the tabs (space highlight)
only uses the :background and the tab-mark will use only the
:foreground. Simpler and with all the flexibility. WDYT?

Thanks again,
Best,
