As you scroll through these photographs, look for the use of color, form, space, light and texture and how all affect the architecture. Stone is combined with stucco and brick, woods are stained and walls are often painted in soft pastels. Shutters are utilitarian and serve to block sun and provide privacy. Note how all the variations compliment one another and there appears to be a uniformity without sacrificing individual tastes and styles. There is a casual randomness of how some materials such as stone and brick are combined, yet there is a well thought out sense of scale and proportion.
You may be surprised to see that very ornate windows are created using a three dimensional painting technique called trompe-l'oeil. Trompe-l'oeil is an art technique that uses realistic imagery to create the illusion that the depicted objects exist in three dimensions.It may be as simple as painting a colored border around a window or door to highlight it.
