Is this possiable?(Floating Combat Numbers)

[badzak94]

Hey i was wondering and i think i would be a cool idea. Is there someway to change the numbers floating above the mobs head that if it is say poison damage you can change the font and color of the numbers so you know it was poison damage?

ex
Bob hits a spider for 100 crushing damage
Bob hits a spider for 12 poison damage <--- this text floating above the mobs head would be a diff font and different color say green
