RGB displays are designed around average human rods and cones. Audio compression is designed around psychoacoustics — what the brain notices vs. filters out in sound, so compression can selectively damage the part your brain throws away anyway.

I have never seen science fiction acknowledge how fucking weird our MP3s must sound and how bizarre the color gamut of photographs on a luminous RGB or reflective CMY(K) display surface (including printed paper) must be to space aliens.

the entire history of paint mixing is like that to some extent. and we don’t necessarily need space aliens for this, human tetrachromats and birds with wider color gamut sensitivity exist

@kistaro it's very fun when you actually bump up again it's the edges of this in the real world. I made a disprosium compound that under some light sources looks colorless, and under other light sources looks purple.

I was very confused when I came into the lab and all of a sudden the colorless compound I've been working with for several days with purple and I couldn't think of any chemistry that would have caused this change (they replaced our bulbs with LEDs overnight)
