What is a colorimeter?

CIELuv color space and CIELab color space are the two most common uniform color spaces in colorimeter. Both color spaces use three components to describe color, and color is expressed by lightness and chromaticity. So, what do colorimeter CIELuv and CIELab mean? What are the differences? The following is an introduction.

As an optical instrument, the colorimeter has different measuring angles according to the different angles of light source illumination. The more common ones are 45/0, d/8 and multiple angles. Colorimeters with different measuring angles have different functions and effects. This article introduces the angles and functions of colorimeters.

As a tool for color quantification, the colorimeter uses the internationally accepted CIELab color space when measuring color, and digitally expresses the color in three dimensions: L, a, and b. This article introduces the range of the colorimeter Lab value and the meaning of the Lab color difference value.

When measuring color, the colorimeter is based on the most widely used CIELab color space, and the color is expressed as Lab values. So, how do you understand the Lab value of a colorimeter? What is the standard for determining the Lab value of a colorimeter? This article introduces the meaning of the Lab value of a colorimeter and the standard for determining the Lab value.

When the paint on the car surface ages, peels off or is damaged, the car needs to be repainted. In the process of repainting, the influence of various factors can easily lead to inconsistent colors after paint application. In order to detect the consistency of the color of car paint, a multi-angle colorimeter can be used. This article introduces the method of measuring the color difference of car paint with a multi-angle colorimeter.

Skin color changes can reflect the integrity of the skin barrier, the sensitivity of the skin, and the skin\'s response to drugs, beauty, and skin care products. Therefore, quantitative analysis of skin color changes is of great significance in dermatology and beauty and skin care work. This article introduces the application of colorimeter in skin color measurement.
