Role Of Color Spaces In Color Measurement Of Objects

The color spaces and color formulas are the two major aspects that are used in the color measurement. The color formulas are basically the method through which the color of any object is represented in the mathematical values. The analysis of the colors is done in two ways, one if visually and the other using color checkers. When colors are tested visually, the accuracy of the test results is dependent on the visual analysis and color perception skills. This can result in a variation of the analysis hence the best way to analyze the color quality of the quality is to use color checkers.

The color checkers work on the basis of the color spaces and formulas. There are several different color spaces that are used for color measurements of different objects. 

CIELAB

The CIELAB color space formula works on the formula of L*a*b. this color space is accepted in laboratories and industries at international level. The values in this color space are calculated on the basis of values of X, Y and Z coordinates which depict the most basic mathematical model of color measurement. 

The values of colors in the CIELAB color space are determined by depicting the colors as the coordinates in a rectangular system. The L* in the system gives the intensity of the color that is darkness or brightness of the color. a* gives the position of the color on the green-red axis and b* gives the position of the color on the blue-yellow axis. 

L*C*h⁰

This color space is also widely used in color measurement and is best for calculation of the color difference of L*C*h⁰. The color space is actually derived from the values of L*a*b*. In this color space, the L* gives the lightness or the darkness of the color; the C* gives the distance of the color from the center of the color space, and the ∆h° is the hue difference that is noted for two different colors. 

Testronix offers the best range of color checkers that are used in industries that help the manufacturers in accurate evaluation of the products and materials with great accuracy and precision.
