Purkinje!Forty-two greens & the race to outlast the sun

Here is the joyful, well-attested, slightly ridiculous fact this whole page exists to show you: as the light goes, greens do not fade together. Your cones clock out and your rods take the desk, and the rods are wild for blue-green. So the warm greens — the chartreuse, the citron, the proud avocado — collapse into mud, while the cool ones sit up and glow. Drag the sun. Watch them change places.
