I would venture to guess that Dumbledore's patronus is a phoenix, I
only have the GOF incident when he calls Hagrid to where Krum had been
stunned and the figure was a silvery Phoenix shaped. 

Carol responds:
Although I agree that DD's Patronus is probably a Phoenix (I also see
a stong Phoenix/Gryffindor or Fawkes/Gryffindor connection), I don't
recall the silvery light that shot from DD's wand as he summoned
Hagrid being Phoenix-shaped. (I could be wrong here; if you have the
quote handy, by all means supply it.) I did wonder, though, when I
read that passage, what kind of spell DD could be casting since it
didn't have any connection with Dementors and was definitely not a
Patronus. What was the silver light and how did Hagrid know it was a
summons? What was the spell he used (he cast it silently, as the more
powerful wizards seems to do as often as not). I wonder if it's one of
the ways the Order members communicate that don't involve the Floo
network (mentioned near the end of OoP). I also wonder how Snape and
Dumbledore communicated on the night of the MoM incident. Maybe we'll
see more of this particular spell.

A note here for what it's worth. We've seen several spells involving
red or green light (also red and green sparks sent as signals), two
spells (apparently) involving silver light, and one (the Phoenix song
with the duelling wands--not sure whether that qualifies as a spell)
involving golden light. Nothing so far involving blue or purple that I
recall. In any case, the color of the light has to be limited by the
range of available colors: rainbow shades (red through purple or
violet) with the addition of silver (or white) and gold. We've come to
associate green light with AK, but surely other spells produce green
light? And red doesn't necessarily mean Stupefy. (Isn't Crucio also red?)

What's my point? I'm not sure. Just that I'm wondering whether the
colors have any significance. Certainly we can't say that green is
evil and silver is good or anything that simple. (That would be
ironic, anyway, since the Slytherin serpent is silver but their banner
is green.) Anyone remember the color, if any, that comes out of the
wand when Fake!Moody Imperios the kids? And does anyone think that the
color of the light has any significance?
