I went through the same thought process years ago and thought, yes black blends in to the room, but they look like speakers bought at Best Buy. I wanted something not flashy, but more "rich" looking. Solid woods weren't available back then, so I went Boston Cherry. I really like them and they work well with just about any colors in your room. I've had mine against tan, white, flat black, grey, and a couple of shades of blue, and they look good wherever they are.
The texture, if I would have to comment on reflectiveness, is more matte than glossy, so in a dimmed room, you will end up getting about the same level of reflectiveness from the boston cherry as you would black anyway since the light is more difused on the surface regardless of color.
