I love my North Face Mica FL 2. It's a light-weight 2 person. It's a really roomy 1 person, and I've spent a couple nights comfortably with my girlfriend in it so it actually can be 2 if you keep your gear out in the vestibules. It has a vestibule and decent sized door on each side. My pack weight is ~3lbs.

It looks like it has a yellow vestibule on the site(I never would have bought it if mine were yellow), but mine is grey. Maybe look around if it's a tent you're interested in and see if it comes in grey or if they changed it.
