Color coding

I'm probably not the first with this idea so I guess that there's a
complex issue behind it but since I couldn't find an answer I just
though to ask:

Wouldn't it be nice to have color coded objects as output of ls()
statement? Functions of one color and rest with other (at least). So
when I issue an ls() I could visually discern different types of
objects.

I often find myself opening old files and spending time figuring which
is which. I know this just means I'm not aoranized, but still...color
coding would help.

You haven't mentioned your platform: you would have to be working in a 
console which supported this, and e.g. the Windows GUI console does not.

Once you know the escape codes to change colour, it would be easy to write 
a listing function which did this.  You would almost certainly have to 
write some C code to find out what the codes are for the current terminal 
(on a modern system via the terminfo database): the GNU ls (part of 
coreutils) would provide you example code.

So, this is project for a package: are you volunteering?
