Need help choosing a color for refinishing furniture?

I am refinishing two pieces of furniture for my living room. One is an oak coffee table (very large and modern). The other is a small antique wardrobe (some may refer to this as a chifforobe) that is about 5 ft tall. This piece is also very square without detail and mirror doors. I'm adding this to the living room for an "anchor" and additional storage. The wall colors are a tan (can't remember the exact name) and one accent wall that is an olive green (this a corner wall with a fireplace and only about 6 feet wide). Couch is a brown leather with black feet and TV stand is black. I was thinking of staining both pieces with an ebony, but I am also considering a color stain possibly a green. I need help deciding. These are two pieces that have sentimental value and I plan on keeping forever so I want to use a color that is versatile. That's why I was leaning toward ebony. However, the green would really add color. Or should I stain the wardrobe one color and the table another???
