Hi!

Short answer:
It describes the missing color. Where Warmth is (very) basically
switching between red and blue, Tint is switching between more and
less green. "Less green" is usually known as magenta. :)

Long:
White balance cannot be set by only one parameter, a lot of light
emitters also a tint toward either green or magenta. See this graph:

Where the temperature tells you where are on the curve, the tint tells
you how far you are on the lines that goes out from the curve.

Hope that clears it up a bit.
