[PLUG] How does 'ls' determine file type for colorization purposes?

[Paul Mullen]

As the title says... How does 'ls' determine file type for purposes of
color-coding it's listings? The man and info pages don't seem to give
any clue.

My question stems from my desire to have files of, say, *.tiff displayed
the same as those of *.tif (truncated file-type extensions are one of
my pet peeves). Currently, the image files with short extensions are
colored some garish pink, while the "proper" extensions are not colored
at all. Argh.
