What should i wear for interview - colour coordination advice please?

Hi. I'm a bloke and i've got an interview. I've got brown shoes so far. I like the brown but i don't want to overdo it by going brown everything. I'd like brown trowsers but what other colours will go with the brown, just so i don't look like a turd when i go for my interview. I'd usually ask my girlfriend but she is away so i have to rely on you trusty folks. Cheers.
