[색의 문법] 동시 대비

Simultaneous contrast: two identical plain ceramic cups glazed in exactly the same neutral mid-grey stand side by side on a table. The left cup stands on a bright lemon-yellow cloth and the right cup on a deep navy-blue cloth; the two cloths meet in a straight line down the center of the frame. Both cups are the same size, same shape and exactly the same grey. Flat even overhead light, plain background. No text, no letters, no logos anywhere.
