Physics of color

This UE covers :

- the fundamentals of colorimetry, which defines an unambiguous measure of color based on psychophysical experiments.

- the principle and practical use of color measuring devices (colorimeters and spectro-colorimeters).

- the principles of color reproduction, particularly in the context of perfumes and cosmetics.

Theoretical ideas are complemented by a significant amount of observation and experimentation in the short practical sessions.

Hourly volumes* :

CM: 12h

Practical work: 8h

Master the basic principles and techniques of color measurement, and the resulting characterization of materials.

Know how to visually evaluate a color, Know how to measure a color according to the different techniques used in the industry, Know how to reproduce a color (simple formulation), Knowledge of the main measuring devices on the market. Good colorimetry practices.
