Dark Forest skin for Midnight Commander ( dark mc colors theme with sufficient contrast )

jult.ini

#  Being unsatisfied with the look of mc in console/terminal windows, I made this for my own use.
#  Version 3.7, subject to change over the years.. <[email protected]>

#   I N S T A L L

#   Put this file (jult.ini) in either of these skin-directories:

#    /etc/mc/skins/
#    /usr/share/mc/skins/
#   ~/.local/share/mc/skins/
#   /opt/share/mc/skins/ (Entware)

#   In order to have MC find it, change the main ini ( usually at /etc/mc/ini or ~/.config/mc/ini ) and set
#     skin=jult
#   under the [Midnight-Commander] section..
#
#   Color-conflicts may arise from the [Colors] section, just delete that from the ini (while mc is not running..)

Thanks. This skin is great.
You don't have to modify anything, to detect skin by mc. It's enough, to make directory (skins) and put this file into this dir. After restart of mc, you will see this skin inside settings. Checked with 4.8.30.
Could you tell me, where is documentation for it.
