A few years ago, I redid my basement stairwell. I removed the carpet from the stairs and painted everything in a lilac and black color scheme.
On the risers, I used black and white adhesive shelf paper.
I liked the result... until I didn't really like it anymore. After a while, I just wasn't feeling the lilac. So I repainted the stairwell in the same grey, black and white color scheme as most of my house.
I used a black and white scroll print paper on the risers.
