Discussion Overview

The discussion revolves around the perception of the sky's color when viewed through orange sunglasses. Participants explore the reasons behind the phenomenon, considering aspects of light absorption, visual perception, and contrast effects. The scope includes conceptual reasoning and exploratory analysis.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant notes that orange sunglasses absorb some blue light, leading to confusion about why the sky appears bluer when viewed through them.
  • Another suggests that while orange sunglasses transmit orange wavelengths, they may also allow some blue light to be transmitted, contributing to the perception of a bluer sky.
  • A participant introduces the idea of an optical illusion, implying that the brain's interpretation of color may play a significant role in how the sky is perceived.
  • Another participant argues that the darker appearance of the sky, due to the absorption of blue light, may lead to a contrast effect that makes the sky seem bluer relative to the surrounding environment.

Areas of Agreement / Disagreement

Participants express differing views on the mechanisms behind the perception of the sky's color through orange sunglasses. There is no consensus on the exact reasons, with multiple competing explanations presented.

Contextual Notes

Some assumptions about light transmission and perception are not fully explored, and the discussion does not resolve the complexities of color perception in this context.

If I rember correctly, the sky seems more blue, when you look through a pair of sunglasses with orange glass.
Why is that ?
can anyone help out here.

Orange glass is orange because it absorbs some of the blue light - but then the sky should be less blue - right ?

Science news on Phys.org
orange sunglasses make everything orange as they mostly transmit light of orange wavelength more than most other visible wavelengths. If what you say is true then it would appear that wavelength of blue light from the sky is also transmitted significantly more than other light although obviously not as much as orange. So while everything is more orange, it's also a bit more blue.

Just a guess though, mind.
 
According to me, there's something connecting the illusion of the eyes.
 
The orange glass preferentially absorbs the blue light. Thus, the sky is seen as darker than you would expect, particularly when compared to everythnig else in your environment. This darker sky looks bluer, but I do think, as you surmise, that this is an interpretation of the brain. The brain sees in contrast. A blue ball next to a red ball will appear bluer than a blue ball next to a cyan ball.

A careful analysis of the absolute colour in the scene will reveal light from the ground to be slightly darker and more orange, whereas light from the sky will be much darker and more orange (not more blue).
 
Thanks DaveC
I will have to buy a pair and maybe try to meassure it.
