Abstract: The short answer is that color change-in general, not just in wood-is chemical change. Woods like cherry and mahogany that richen and deepen in color with time and exposure to light will change much more quickly in direct sun than in the dark or under indoor lighting. Because light speeds the reaction so much. most people think that light is the only factor. but it is not strictly required the interior of a cherry board will eventually end up the same rich brown as the surface. despite never seeing a single photon. though the process may take decades if the wood is kept in the dark.
