> have to memorize the order and positions of different hues. Almost everybody is familiar with the rainbow, and it's a physical real-world relatable concept. Even if you can't name the color order from memory, it's intuitive what changing the hue left or right does. Unlike RGB, where it's basically impossible (for regular people) to predict what changing one component will do to the final color.
