FAQs About NH300 Colorimeter
Opaque liquids and powders can be put into a cuvette for color measurement.
Colors look different under various lights mainly because of metamerism—a phenomenon where two colors that match under one light source fail to match under another, caused by differences in the spectral composition of light.

Different lighting varies the color perception of objects. Warm light, like that from incandescent bulbs, tends to make colors more yellow, while daylight presents a bluish tint. Our color vision system plays a compensating role using a mechanism called color constancy.
Every light source emits light with a unique "spectral fingerprint" (i.e., the range and intensity of wavelengths it contains). This directly affects how an object’s surface reflects light and how our eyes perceive its color.
Color is measured using devices such as colorimeters, spectrophotometers, and spectroradiometers. Colorimeters are easier and good for simple color quality tests. Whereas spectrophotometers yield detailed spectral information. Hence, suitable for laboratories and industries.
Many people might answer "with the human eye", but this is actually not comprehensive. The human eye cannot accurately distinguish the colors of similar objects. Furthermore, everyone's perception of color varies. Therefore, people have developed color measurement tools based on the CIE color system.
Currently, there are two main types of commonly used colorimeters, as follows:
Colorimeter - It is an ideal choice for quality control (QC) on production lines, used to detect color differences.
Spectrophotometer - It is suitable for the development of color characteristics and color analysis in laboratories.
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:
Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).
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.
