How do you define Color Science?

The science of color, from a sensory definition, is the way in which light is reflected on the surfaces of objects; color is that part of how visible it is reflected from a plane and the amount of light, which is reflected or absorbed from a surface, determines its color.

Therefore, the study of color is based on maintaining the projection of objects or samples, in a detailed and appropriate way, from different light sources. The intervention of the color evaluation box as a study tool, allows simulating from different principles of light, the objective evaluation of shades and tones at any time and from any perspective.

The purpose of the tool, also known as color combination box, color combination cabinet, viewing booth, etc., provides users, meet color difference tests, either for lighting manufacturers, graphic arts visualization, photography, textile, printing, ceramics, plastic, automotive and laboratory.ย 

Color Study

In any color evaluation, parameters such as subjective processes are involved, which must be standardized for the process to be reliable, and have to do with the light source, the observer and the object to be evaluated.

It should be noted, that the light source, can mean a drastic change in how the color of an object is perceived. For color evaluation purposes it is very important to define the type of illuminant under which observation will be performed, as a sample may change from having an acceptable color, under a given illuminant, to an offset color, under another illuminant, including: D65 Day Light, TL84, Cool White Fluorescent CWF, Incandescent A light, etc.

Also, among the parameters of the evaluation of colors, it has to do with the observer, since he is the person in charge of controlling the tool and has experience to have elements of judgment, when deciding between accepting a color or rejecting it. In this sense, the object to be evaluated is achieved depending on the physical presentation of the object and its disposition.

Importance of Color Assessmentย 

The importance of color science, through an evaluation box, is responsible for calculating and manifesting the appearance of products, as well as,ย sort human visual perception, with color values. The color evaluation box’s primary objective provides standardized, uniform viewing environments to appreciate color variations, detect illumination sources, and accurately participate in an entire supply chain.

Accordingly, it is recommended that

  • The environment where the study is carried out by means of the evaluation box should be a laboratory with an adequate level of lighting.
  • Use a single type and mark of luminaire (spotlights or fluorescents) to avoid variation of the color of the light source.
  • The arrangement and height of the luminaires should be adequate.
  • Do not exceed the use of the evaluation box, because it may cause variations in hue and hue.
  • Store samples and color charts appropriately.

The method of evaluation, the arrangement of the samples, the types of illuminants, the acceptance criteria and ranges, etc., define the perception of the color of the samples to be evaluated.

However, environmental and personal factors such as excessive heat, poor ventilation, work stress, fatigue, emotional problems, health problems, etc., affect the correct performance of the observer. Care should be taken to ensure that such factors are under control before performing such tasks.
