I think this is two logical changes into one.

I've been thinking that this method of loading the script is not the
best; we should probably have a list of locations where distributions
usually put this file. So if we could avoid the creation of of a new
file, that would be great.

This is the only real difference with bash colors, no? I think it's
overkill to create a new file, and load the old one, only to override
part of a function. We should probably start with everything in the
same file, and only later if we find it's necessary, split.
