Question

We've upgraded to Sympa 6.2.72 and have realized that the ability to set color parameters in sympa.conf is no longer available (color_0, color_1...)

https://www.sympa.community/gpldoc/man/sympa_config.5.html#color_0--color_15

It seems possibly related to this conversation?
#1424

At any rate, is there guidance on how we can continue to specify color codes for those variables systematically rather than hand editing those colors through the GUI? Thanks y'all!
