Componentes básicos de la medición del color

La percepción visual del color está influenciada por nuestras preferencias de color individuales, que dependen de factores personales (estado de ánimo, edad, sexo, etc.), el entorno (iluminación, entorno, etc.), así como nuestra capacidad para comunicar el color y las diferencias de color. Un color se ve diferente en los grandes almacenes (iluminación fluorescente blanca fría) que en casa (iluminación incandescente cálida). Para garantizar un color y una apariencia consistentes en todas las circunstancias posibles, es esencial estandarizar la fuente de luz, el observador y comprender los datos de remisión espectral del objeto. Esta información será la base para el cálculo de los datos colorimétricos, ya que se utiliza para la comunicación del color y el control de calidad del color en la producción.

Color Difference Equations for Solid Colors

It is now almost 100 years since, in 1931, the CIE Yxy chromaticity color space was defined by the “International Commission on Illumination (CIE)”. To overcome its limitations of not being uniform, the CIE recommended two alternate color spaces since then: CIELAB (or CIE 1976 L*a*b*) and CIELUV (or CIE L*u*v*). They are based on the opponent color theory of color vision, which says that two colors cannot be both green and red at the same time, nor blue and yellow at the same time. During the last years developments of new color difference equations and color spaces were carried out. Their goal was to improve the correlation between visual perception and instrumentally measured values. Additionally, they wanted to permit the use of a single number tolerance for all colors.

Color Measurement of Fluorescent Colors – a CHALLENGE

The world around us is bright and colorful. Neon colors in particular have been back in trend for several years. The prerequisite for this is the use of fluorescent pigments in the paint, plastic and many other industries. Although these have been widely used for many years, the quality control of fluorescent material still remains a major challenge. The following article describes theoretical background of fluorescence, why a standard spectrophotometer is not suitable for the quality control of fluorescent material and what possibilities the new combination of spectrophotometer and fluorimeter offers - especially with regard to predicting the lightfastness of a material.
