What does it mean that color a “visual phenomenon”? Does color not exist outside of our brains?

Fun fact. Magenta isn’t a color…. Sort-of.
So yes, colors usually exist as a specific wavelength of light and have properties outside of just our brains. Except magenta does not exist as a wavelength of light. So what’s going on there?
Well we have cones in our eyes for seeing red light, green light, and blue light. What Magenta is is seeing red and blue light at the same time. Which you’d think your eyes would average out and show us green. But they definitely don’t do that, instead we see magenta.
And magenta isn’t the only color that doesn’t exist that we can see. There are several “impossible colors” that are also kind-of interesting. And in that sense…. Yeah your brain makes up what colors look like even if they usually have real-world properties.
