There’s nothing in the sky that’s actually blue. You won’t get blue stains on an aircraft. It’s because of weird radiation thing that happens in many contexts.

It’s because of weird radiation thing that happens in many contexts. Including the irises of people with “blue” (transparent) eyes.
- naasking 4y agoI think you have a very weird way of thinking about colour. Saying the sky is blue is no different than saying the ocean is blue. Water doesn't look blue when you get something wet either, and yet the ocean is blue. A "weird radiation thing" is exactly how colour works.
- tshaddox 4y agoI have a blue blanket that doesn’t leave blue stains on anything either. That’s not a robust definition of what it means for something to be a certain color.
