False color is a misnomer. It’s light outside the visible spectrum remapped to RGB. RGB itself is false color that happens to align with the light sensitive cells in our eyes. Save for pure red, green, or blue images, all color images don’t actually match reality. An alien looking at an iPhone would see non sensical colors.
No that's not correct, "false-color" is a widely recognized term for mapping non-visible light colors onto RGB, as opposed to "true-color" which maps visible colors to RGB in a way that closely approximates how our eyes would see the thing being captured.
