SUMMARY

The discussion focuses on interpreting the L, x, y values in color transmittance reports related to coatings on transparent sheets. The L value represents luminance (Y), while x and y correspond to chromaticity coordinates in the CIE 1931 color space. Participants suggest researching "color space" and "xyY" for deeper understanding. The conversation emphasizes the importance of accurately interpreting these values for effective color measurement.

PREREQUISITES
  • CIE 1931 color space knowledge
  • Understanding of color transmittance measurement techniques
  • Familiarity with luminance and chromaticity concepts
  • Basic knowledge of optical coatings
NEXT STEPS
  • Research the CIE 1931 color space in detail
  • Learn about color transmittance measurement methods
  • Explore the significance of luminance (Y) in color science
  • Investigate the application of xyY coordinates in color analysis
USEFUL FOR

Color scientists, optical engineers, and anyone involved in color measurement and analysis of transparent coatings will benefit from this discussion.

Dear folks

The case is this... to measure the color transmittance through a coating on a transparent sheet... and the values are in L, x, y [thought there should be a "y" but its not in the report]...

Can anybody shed some light on how to interpret L, x, y in this report ?

Thanks !
