I was looking in /usr/bin tonight and saw this:
The symbolic link in cyan / red is a curiosity:
lrwxrwxrwx 1 root root 25 Jul 19 04:48 ubuntu-core-launcher -> ../lib/snapd/snap-confine*
As I don't use snapd yet (Ubuntu 16.04 / Unity Interface) I'm not really concerned but I'm curious if anyone else has encountered this strange coloured link and what it means with all the dangerous looking red?
As sergiy mentioned in comments it is a bug with ls not filling in colors properly when window size causes a line to wrap to the next.
You can see it here by changing the window size for sudoedit:
As for the color red itself it's because root becomes the user due to access permissions:
$ llocate /lib/snapd/snap-confine
ACCESS OWNER GROUP SIZE MODIFIED NAME (updatdb last ran: 2018-09-26 17:45:05)
-rwsr-sr-x root root 98440 Jul 19 04:48 /mnt/clone/usr/lib/snapd/snap-confine
-rwsr-sr-x root root 85832 Nov 30 2017 /mnt/old/usr/lib/snapd/snap-confine
-rwsr-sr-x root root 98440 Jul 19 04:48 /usr/lib/snapd/snap-confine
Notice root has access rights rws and group has access rights r-s. Everyone else has r-x execute rights. See: rwx Versus rws
Scrolling down further there is another bug example in orange this time:
