Psychology

Dark greens evoke dense forests, institution and permanence — think library walls, old maps, and military insignia.

History

The pigment verdigris — a green formed by the corrosion of copper — was widely used in medieval manuscripts and early oil painting, despite its tendency to darken over time.
