It happens when the tannins in the wood interact with moisture or specific chemicals (like paint). The tannins are essentially released and find themselves on the surface of the coated wood, resulting in yellowish stains or blotches. Tannin bleed shows up more when using light colors, especially white.
The best way to dull down a bright color is to add a bit of its complement. The complement of yellow is purple, so a bit of purple will dull down the yellow. If you want to lighten the color, add white.

Light, and lack of light, can affect how well paint color is preserved and how quickly it yellows. In the case of yellowing due to lack of light, chromophores are to blame. Chromophores are produced as oil-based paint dries, and are a natural part of the process. Chromophores are broken down by exposure to light.
