Here is the plan:
Trim: All white, except for the handrail and newel posts, which will be stained a glossy black
Wall color: Sherwin-Williams Offbeat Green

Decor: Framed posters and photos on the walls and a chandelier covered in crystals that our neighbor gave us. I want to paint it, but I'm not sure what color yet. I might go with black, white, or gray since the wall color is so strong.
Problem: The stairs themselves! We got a quote to have it carpeted, but now that I'm thinking about it, I don't know if I want carpeted stairs! Style aside, I love the way they creak loudly when someone walks on them. It makes me feel safe at night, and it's just sort of a weird comforting sound any time I hear Dustin walking on them or walk on them myself. I'm also concerned about my willingness to vacuum stairs. I am notoriously lazy, and although I don't mind vacuuming, I HATE to vacuum stairs. That may not mix well with my love for our 4 furry pals!
Here is what we're working with. (Please disregard the wallpaper, drapes, and weird bathroom with a basket on top; none of these things are there anymore!)

So should I paint them white with a painted runner? I LOVE this look, but I don't know exactly what kind of paint to use. We painted the stairs to the attic using black porch/floor paint, and I don't love it. It's not glossy enough... but then won't gloss make it slippery? What if I use a regular latex paint with a coat of water-based poly on top? Wouldn't that be just like the coat of poly that is (or was haha) on top of the stain that's already there?
Here's the look I want (but not red!)

And OMG I just found this while searching for the above photo:

I LOVE that idea, but with white treads!
And here are some colored treads with white risers:

So should I forego the carpeting (which will subtract $250 from the cost of the carpet installation in the bedroom and upstairs hallway, yay!) If so, what should I do instead?!
Update: I just got the new quote and it actually subtracts $370 DOLLARS from the carpet cost!!!
