Colours of objects produced by light due to reflection & absorption

Click For Summary
SUMMARY

The discussion centers on how the colors of objects are influenced by the absorption and reflection of specific wavelengths of light. Participants highlight that different light sources, such as incandescent bulbs and fluorescent lamps, emit distinct light spectra, which can alter color perception. For instance, sodium vapor street lamps significantly affect how colors are viewed. Understanding these differences is crucial for accurately interpreting colors under various lighting conditions.

PREREQUISITES
  • Understanding of light spectra and wavelengths
  • Knowledge of different types of light sources (incandescent, fluorescent, gas discharge)
  • Familiarity with color perception and its relation to lighting
  • Basic principles of reflection and absorption of light
NEXT STEPS
  • Research the spectral output of incandescent versus fluorescent lighting
  • Explore the effects of sodium vapor lamps on color perception
  • Study the principles of color theory in relation to light sources
  • Investigate the impact of different lighting conditions on photography and visual arts
USEFUL FOR

This discussion is beneficial for lighting designers, artists, photographers, and anyone interested in the science of color perception and its dependence on various light sources.

Colours of objects produced by light due to reflection & absorption!

Hi fellow members!
We know that colours of our surrounding things is due to the absorption & reflection of particular wavelength of light. But we also see same colours of objects in bulb light aur tube light. Do they also have seven wavelengths of light as light have?
Thnx!

It depends on the light source. An incandescent source will produce a very different spectrum than a fluorescent or gas discharge lamp. You may have noticed how a sodium vapour street lamp affects your perception of colour, for example. This page explains the different spectra for these lamps
