The nature of light from colored(visual) materials

Click For Summary
SUMMARY

The discussion centers on the visual perception of color and the underlying physics of light interaction with materials. It clarifies that color perception arises from the absorption and reflection of specific wavelengths of light by materials, rather than being an inherent property of the materials themselves. The conversation references the contributions of notable figures such as Edwin Land and Thomas Young, emphasizing that color is a perception influenced by complex interactions of light rather than a straightforward physical characteristic.

PREREQUISITES
  • Understanding of light wave properties and wavelengths
  • Familiarity with color theory and perception
  • Knowledge of atomic absorption and emission processes
  • Basic principles of optics and material science
NEXT STEPS
  • Research the principles of atomic absorption and emission in materials
  • Explore color theory in depth, focusing on the perception of color
  • Investigate the contributions of Edwin Land and Thomas Young to color science
  • Learn about the physics of light waves and their interaction with different materials
USEFUL FOR

This discussion is beneficial for physicists, material scientists, artists, and educators interested in the science of color perception and the interaction of light with materials.

My question stems from the visual perception of color. First I'd like to clarify what we're seeing. When we see that a material is a certain color does this mean that it's constitute atoms are continuously absorbing certain wave lengths/energy levels of light and blocking out/bouncing the left over wave lengths to our eyes? or does the light that the atoms emit after absorption have more to do with it? My question was really sparked by wondering why colors are continuous. Are materials constantly absorbing/bouncing off certain wavelengths? or is there a continuous exchange of absorb/emit? or both? or neither? or somewhere in between? lol just curious. I couldn't exactly find the answer of what wavelengths we actually see and why...

This is a very complex question, and it's been studied by many famous people, like Edwin Land and Thomas Young. antistrophy's website is quite good.

The key concept is to understand color is a perception, not a physical property. Different physical properties of light contribute differently to this perception.
