House Colors in the Movie -- HELP!

[windyroselane at yahoo.com]

If we're attempting to make scarves for all the Hogwarts' houses in 
the movie, what colors are they?

There are three of us guessing on this, but we need help. Two gold
and two silver? As in maybe:

Gryffindor
red (burgundy? maroon?) / gold

Hufflepuff
yellow (brown? - but their quidditch capes are yellow) / gold

Ravenclaw
blue (royal) / silver (light blue?) -- one of the scenes has a clutch 
of Ravenclaws passing in the background in scarves but we can't tell 
if the light color is gray [silver] or light blue

Slytherin
green (very dark pine) / silver (gray in scarf)
