Patina

Buildings made out of wood then painted make great subjects. Add the sun baking the painted wood day after day and you've got patina.

Patina is when an object changes over time due to the elements. Painted wood is one of the most favorable to get a beautiful patina. That's because the paint often fades, blending in the woods color and texture to create a new type and even prettier surface.

Other surfaces such as glass and steel don't offer a good patina because the surfaces don't really move onto other more attractive colors like painted wood does. Steel rusts and glass can turn into an ugly off white color.
