When do we use marron or brun for the color brown? 

Why is it "je suis nouveau ici" instead of "je suis nouvel ici"? I thought it was nouvel before a vowel.

Hi, 

I was wondering if somebody could explain to me please when one should use 'Y' vs using 'En'.
For example, in trying to say "She thinks of it" - could it not be "elle y pense" or  "elle en pense"? 
Is it just determined by the context? Ie if the sentence before used De use En or if it used A use Y? 

Any help greatly appreciated.

I am searching for the use of s'intéresser à ...versus interesser quelqu'un. Could you please provide some examples and explain how these two forms should be applied. Thanks heaps.
