Consistent naming conventions

Consistent naming conventions:

So far, variables are named like this:

$gray          = lighten($black, 50%)
$gray-light    = lighten($gray, 50%)
$gray-dark     = darken($gray, 50%)
$gray-lighter  = lighten($gray-light, 50%)

The color is gray 1st - and 'light' 2nd.

"Themes" are named like this so far:

light-theme() or dark-theme()

Should they be theme-light() ?

This isn't the biggest deal ever... but these things should be intuitive so I don't have to ever go check for, "Well, is it light-gray or gray-light?

Another place where this exists is extra-small-type(). I definitely do not want to write type-small-extra() ... so maybe that's one vote for descriptor first
