Hi herve,
MultiCommander has color settings to all components, so you can create your own theme.
Just go to Configuration > Core Settings > Colors
and Configuration > Explorer Panel Settings > Colors
I mimicked Windows 10 Explorer's colors so it feels natural. To do it I used this excellent program
http://www.iconico.com/colorpic/You can also configure colors on files and folders based on rules, wich in turn can be based on a multitude of rules. Personally I configure it to show empty files as red, files modified on the last 24 hours as green and up to 1 week as blue.
If you feel your theme is usefull to others you can copy the settings on the text files and share on the forum.
I think it would require MC to have a import/export theme to be compatible with

If you need further help, please tell.
