L * a * b *, also known as CIE-lab, is one of the most common uniform color spaces for measuring object color which proposed by CIE in 1976. It is a color space established to overcome that the equal distance on the YXY color space diagram is not the same color difference we observed. In this color ...
What is XYZ

2022-06-23 18:17:59

Modern theory of color vision holds that there are three kinds of color sensitive pyramidal cells on the human retina, which are sensitive to red, green and blue colors respectively. The process of color vision can be divided into two stages. In the first stage, the three kinds of pyramidal cells on ...
How to measure gloss

2020-06-12 08:58:47

Gloss is the surface characteristics of an object, which depends on the specular reflection ability of the surface of the object to light. Specular reflection refers to the reflection phenomenon where the angle of reflection is equal to the angle of incidence. The greater the value of Gloss, the ...
