The peacock's colors are made of light
In 'O Pavão,' Braga reports reading that the peacock's dazzling colors come not from pigment but from tiny bubbles in its feathers that refract light. He reads this as the great artist's secret, reaching the maximum of nuance with the minimum of material, and then applies it to love. It is a concrete case of splendor produced by arrangement and light rather than by accumulated substance.
