Linux Files and Folders distinction


on the screenshot below, I noticed Folders have different colors, I am not sure what 's the reason:
The blue and light blue are folders.
the ones with .extension are files, they are either green or just plain white on black

I was just wondering if there is any Rules about  that .

Thank you

The colors are selectables and are stored in the environment variable: LS_COLORS,  colors can be disabled   --colors=never or --colors=always default is --colors=auto meaning if stdout is a tty  coloring will be done and through pipelines it isnt.    ls | cat    will remove colors.
Besides coloring ls can also add suffixes to filenames..  (ls -F   or classify files).

Folder/
Symbolic-link@
etc.

You can find more in:  man ls
