Movie uniforms - A Question and a suggestion

[Firebolt]

No: HPFGUIDX 3311

Hello,

I saw the movie stills with the Hogwarts students in uniform the other day (thanks to whoever put them up in the Files section!), and I remember someone asking how they had the House-color sweater trim before they were Sorted - my suggestion is that maybe the trim is purple (which I'm guessing is the Hogwarts color, seeing as it's the color of the letter's seal) until they get Sorted, and the trim magically changes color?

Also, I'm wondering - does it really make sense to have variations in uniform for the different houses? Because I'm assuming that by the time we get up to CoS, Harry and Co. have thorough experience in identifying Houses, even if the colors might be really close (i.e. Ravenclaw and Slytherin) - so how come they mistook Penelope Clearwater, who would have Ravenclaw blue trim, for a Slytherin during the Polyjuice incident?

Rather inane post, I know - but I was wondering.
