How to read this comparison
Delta E measures how far two colors sit apart to the eye. Under 2, most people can't tell them apart on a wall. Over 5, they read as clearly different colors. LRV tells you how much light a color reflects. In weak light, an LRV gap usually changes the room more than a small hue shift.
