The picture areas marked with circles have the following color coordinates in the CIE-L*a*b*-system:

  L* a* b*
woman left 75.27 19.45 27.46
woman middle 78.04 12.50 16.65
woman right 83.26 10.18 13.49

FAQs About  Other Charts

In industrial production and quality control, color consistency is one of the core elements determining product quality. Whether it is the metallic paint for automobile coating, the dyeing effect of textile fabrics, or the ink matching in packaging and printing, subtle color deviations may lead to cost waste or damage to brand image.

The LAB color space defines colors with a three-dimensional model:

  1. Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).

  2. Hue and Saturation (a and b):

    • The a-axis represents the red-green tendency, with positive values leaning towards red and negative values leaning towards green;

    • The b-axis represents the yellow-blue tendency, with positive values leaning towards yellow and negative values leaning towards blue.

It is a globally recognized standard and supported by most modern color measurement equipment. Color is quantitatively analyzed by measuring Lab values with instruments.


The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.

The color may be quantified in L*a*b* (CIELAB units), RGB values, CMYK (printing), and ΔE (color difference). Colorimetric assessment measures also apply spectral reflectance and absorbance (A), particularly in liquids and solutions.

To extend the life of a haze meter, keep the instrument dust-free and clean, regularly calibrate it, and control for a stable dry storage. For better results, avoid letting the optics dry, and leave the meters under sunlight. For optimal performance, have the meter professionally serviced once a year.

Measuring zinc coating thickness is most commonly using magnetic induction. The gauge measures how far the magnetic probes are to the metal base under the zinc. This is the most reliable way to measure the thickness and the preservation of the galvanization.
