Blue has totally different effects, depending on whether it is bright or dark. In nature, blue is a colour of the sky, sea water and some precious stones and minerals like lapis lazuli, azurite or vivianite. Costliness and difficulty with creating blue pigments made this colour rather rare in architecture. (Prussian blue, the first modern, artificially produced blue pigment, appeared only in 1704!).
Blue in combination with white is a typical colour of Greek island architecture and many port cities around the world. In Poland blue is associated with the tradition of painting wooden logs in rural areas, mainly in southern Poland. Light blue gives the impression of sterility, optically enlarges the space, provides the impression of depth and distance, and at dusk, as a result of Purkinje's effect, comes to the fore. Blue on the facade will be harmonious with white and grey - both bright and dark. Blue is also compatible with brown, enlivening them and providing them with new image. Also, it is interesting when combined with wood - both light and exotic with red admixture.
