In order to create a cohesive look for the chairs, I had to paint the chairs so that they were identical, despite each being built different.
Basing the colors off of 4 of the chairs being used, I painted the other 6 to match. I created a dark brown for the primer, and then added layers of orange, red, and blackish-brown washes. This not only helped match the coloring, but mimiced wood graining.
I finished it with a gloss to give it the shine it needed.
I repeated this technique with the piano bench being used.
