Apropos color management and icon themes, etc, David Revoy addresses how
color management further down in his annual GNU/Linux guide about his
professional work station:

" Debian 12 KDE Plasma: The right GNU/Linux distribution
for professional digital painting in 2024. Reasons and
complete installation guide. "

The color management instructions seem to work on Devuan, though I lack
a colorimeter to do the rest. I presume he would benefit from Devuan
over Debian for reasons we already know.
