black pianos, it's a classy look and apparently dirt is less noticeable

No pianos! Im trying to get rid of the upright one in my home, currently. No one plays it anymore. 😑

With white, every mark, minor imperfection in the shape, etc. stand out, and also white looks cheap. So I guess black. But my favorite is the piano we had when I was a kid--it was black with white speckles.

Until recently we had two brown pianos, so I guess that's a color you forgot to mention!

Synthesizer

Neither.

Why not both?

Black like my soul
