Not all white light sources are perfectly white. They have different color power distribution in uneven white spectrum, often correlated by color temperature: cool or warm. Photo: Graphical representation of color temperature in visible spectrum. Source: Dariusz Kowalczyk, License: Creative commons attribution The correlated color temperature (CCT) of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source.  Color temperatures over 5000 K are called "cool colors" (bluish), while lower color temperatures (2700–3000 K) are called "warm colors" (reddish). This color temperature of electromagnetic radiation emitted from an ideal black body is represented in Kelvin. Sensegood Spectrophotometer To achieve true color reflected from the object, balanced white light source must be applied.  Sensegood Spectrophotometer  is equipped with robust light source – Complementary compensating full s

Living room objects in warm and cool white LED lights. Image source:  integral-led What is full spectrum light? Full-spectrum source produces light throughout the entire visible spectrum. It is a neutral white light that has power distribution in all visible color wavelengths from 400 to 700nm. Spectral distribution of different indoor light sources Image source: Kim, Soyeon & Jahandar, Muhammad & Jeong, Jaehoon & Lim, Dong. (2019). Recent progress in solar cell technology for low-light indoor applications. Current Alternative Energy. 03. Why objects seem different in different light sources? Not all white light sources are perfectly white. They have different color power distribution in uneven white spectrum, often correlated by color temperature: cool or warm. Object absorbs or reflects colors depending on its own color properties and the color distribution of the applied light source. Objects appear redder under the illumination of warm white LEDs or in light during sunr

This article addresses following two aspects: What is the difference between Colorimeter and Spectrophotometer? Which color instrument is the best for my application? What is the difference between Colorimeter and Spectrophotometer? One will have different perception of color red when said red Ferrari and red apple. This tells all about need of accuracy in distinguishing the colors. Each color with all possible shades has to be uniquely represented in digital or say numerical value. Colorimeters and  spectrophotometers  are the two types of color measurement instruments that are used to measure the color. Color measurement is an essential part of a production process in every industry where color accuracy and consistency is important to maintain the product’s quality and brand reputation. Understanding the factors that distinguish spectrophotometer from colorimeter can help you determine the instrument that suits best to you to optimize your color management workflow. Colorimeter
