An appreciation for airport architecture is a fine thing for a constant traveler to develop. Learning to appreciate the beauty in angles, curves, light, impact - the specific visual language and the visceral feeling of place. The ability to experience moments of solitude, calm, or delight in an otherwise hectic environment never goes unnoticed.
El Aeropuerto Adolfo Suárez Madrid-Barajas is easily a masterwork - clean, airy spaces to diminish inklings of claustrophobia; graceful, swooping curves and warm golden wood to drive out the sense of the clinical; playful and practical dashes of color to draw in the eye and give weary travelers an idea of how much farther they have to walk.
While the building could easily lend itself to moody monochromatic abstract detail shots, it seems a crime to eschew its color and not celebrate it as it is.
