Weirdness in "ls" colorization

[Ron Johnson <ron.l.johnson@cox.net>]

Here's a window-shot of some auto-colored files.  Note how one 
directory's flacs are colored green and the other directory's flacs 
are cyan(?).

My system is a relatively up-to-date Sid, and I've not fiddled with 
the colors.

$ alias dir
alias dir='ls -aFl --time-style=+"%F %T"'

TIA
