Color transmittance measurement

[metalrock]

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 !

Try to google "color space" or "xyY".
I believe your L stands for Y- the luminance component.

Dear reader,

Color transmittance measurement refers to the process of measuring the amount of light that passes through a coating on a transparent sheet and how that light affects the color of the sheet. The values of L, x, and y represent different aspects of the color transmittance.

L represents the lightness of the color, with higher values indicating a lighter color and lower values indicating a darker color. This measurement is based on the CIE L*a*b* color space, where L* represents the lightness dimension.

The values of x and y represent the chromaticity coordinates of the color. These values indicate the hue (color family) and saturation (intensity) of the color, respectively. The x and y coordinates are also based on the CIE color space, with x representing the red-green axis and y representing the yellow-blue axis.

In summary, L, x, and y in the report refer to different aspects of the color transmittance, including lightness, hue, and saturation. I hope this helps to clarify the interpretation of these values. If you have any further questions, please feel free to ask. Thank you.
