Alexis Madrigal on a mulberry leaf growing in his backyard.
In the shade, the leaf is solid and waxy, reflective—the blue sky right now is laying on its the ridges. The texture is so singular, so perfect that it reveals a new dimension of failure for our digital cameras. The lustrous sheen is inseparable from this particular green, and it cannot be captured. The leaf is not iridescent like an abalone shell; it doesn’t reveal rainbows through optics. But it should be in that same magical category! This is a green that reveals the whole spectrum of green and suggests that it might run beyond our perception. This is beauty. My eyes find the leaf from all the angles of our yard.
Emphasis mine.
