I have dark brown furniture in my living room. Would light green walls (think sage) & dark brown carpet go?

I have a chocolate colored leather sofa and a dark cherry dining table. I would like to add some color by painting the white walls in my living room to a light sage green color. My only concern is what color carpet to select. Since I already have a brown furniture, would brown carpet be too dark? I have a toddler, so light colors like cream or beige aren’t an option. And I would prefer carpet over a wood floor for his sake. Thanks for any suggestions!
