Blue is a colour of constancy, a hue that often symbolises dependability and conviction. As a colour range, blue offers countless possibilities, from azure and brilliant electric blues to warm and vital blues. Darker, deeper, inky blues, are especially thought-provoking, and represent depth and balance, quietude and presence of mind. A darker blue has restorative properties, ideal for quiet interiors and moments of calm.Forgetting fads and trends, blue is a perennial colour, and used wisely, darker, deeper blues will enrich any interior space.Galvão by Arriba ArquitectosGalvão is a Lisbon apartment by Portuguese architectural practice Arriba Arquitectos that features a dark blue colour throughout.
