Why can't we set the color in the col tag?

Question

I just came across a use case where it would be useful to create a tag col:

In this particular case, I wanted to set the column colorcolumn "Mail Name", but it turned out that it does not work or is not allowed. But it’s background-colorallowed, although it makes me wonder why colornot.

I checked the specification ( http://www.w3.org/TR/html5/tabular-data.html#the-col-element ), but I did not find any useful information. I know how to do the same effect only with CSS, I'm just wondering if anyone knows why this is happening?
