Download archive with the skin. If the mc version is greater or equal 4.7.0-pre3 you should download and install this version:
http://zool.in.ua/soft/bluemoon/bluemoon-0.01.tar.gz
Unpack the skin to "~/.mc/skins/". On your distribution this might be below ~/.config/mc
A q&d workaround is to copy it over the default.ini for example /usr/share/mc/skins/default.ini and adjust the permissions
Exit from all your mc instances and find in your ini-file ("~/.mc/ini") in section "Midnight-Commander" variable named "skin" and change the value of it to "bluemoon".
Find in your ini-file in section "Colors" variable named "base_color". Delete or comment it.
Run mc and enjoy.
