Wood is brown because it absorbs photons that appear brown. The color of an object is determined by its chemical makeup and its quantum mechanical interaction with light(photons). Wood is mostly carbon in chains with hydrogen and some other elements like nitrogen, oxygen, and trace minerals. The makeup of these chemicals absorb brown light that is reflected back as brown. Sincerely, Tom "Red Dogwood" Cull
