HOW CAN YOU SAY THAT. OH MY GOD THAT SO JUDGEMENTAL. PURPLE IS REAL. PURPLE IS MORE REAL THAN THE OTHER COLORS. IF A COLOR WANTS TO BE PURPLE IT CAN! GOD YOU JUDGEMENTAL FUCK
Facepalm. There are two kinds of purple. The one that's a superposition of red and blue, and the one that's actual 400ish nanometer light at the opposite of red in a rainbow. Our eyes cannot see the difference, but many cameras can. If a camera reproduces a purple correctly then that purple is a red+blue mix, the cam picks up both components easily. But often, something that we see purple looks blue on photos. That's because it's a true purple that's too high in frequency, the blue sensor picks it up but not the red one.
