Sorry, this can't be done with the current versions -- colors are either =
atomic or whole-object properties (with a couple of minor exceptions).  =
The only way around this right now is to distribute the states you want =
to show over a set of objects with different colors:

isomesh m1,map1,1.0,state=3D1
isomesh m2,map2,1.0,state=3D2
isomesh m3,map3,1.0,state=3D3

color red,m1
color blue,m2
color green,m3

Text objects are brand new, and can only be built right now using =
compiled graphics objects (CGOs).

CGOs are always associated with specific states, so adding a label which =
changes during the course of a movie would be straightforward, except =
that text objects are completely undocumented.  Here is a start:

# REQUIRES PyMOL 0.80
# save as cgo_3Dtext01.py

from pymol import cmd
from pymol.cgo import *
from pymol.vfont import plain

cgo =3D []

axes =3D [[2.0,0.0,0.0],[0.0,2.0,0.0],[0.0,0.0,2.0]]

pos =3D [0.0,0.0,0.0]
wire_text(cgo,plain,pos,'Hello World',axes)

pos =3D [0.0,-3.0,0.0]
cyl_text(cgo,plain,pos,'Hello Universe',0.10,axes=3Daxes)

cmd.set("cgo_line_radius",0.03)
cmd.load_cgo(cgo,'txt')
cmd.zoom("all",2.0)
