At you say "higher frequency light, like purple..." But no wavelength of light is "purple" (or more technically "magenta", since purple is just desaturated magenta in the same way that brown is desaturated orange). Magenta/purple is what we see when our eyes are simultaneously receiving blue light and red light, without much green light. It's a color that's invented in the brains of animals that have 3 color cones (like humans), which doesn't correspond to any one wavelength.
