FAQs About NR145 Colorimeter

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.

object_Colors_look_different_under_various_lights1

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.

The "accuracy" of a colorimeter refers to how closely its measurement results align with the true values, primarily influenced by systematic errors and random errors, how closely its measured color data (e.g., Lab values, density) aligns with the true color properties of a sample or certified standard. Specifically, it includes key indicators such as color coordinate accuracy, luminance accuracy, and data repeatability.

It reflects the instrument’s ability to minimize deviations caused by component variations, environmental factors, or calibration drift—ensuring results reliably represent the actual color, which is critical for quality control and brand consistency in industries like printing, food, textiles, paint and coatings.

Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

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.
