Physics of color

This EU addresses:

- the foundations of colorimetry, which allow to define an unambiguous measure of color from 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 an important part of observation and manipulations during the practical sessions.

Hourly volumes* :

CM : 12h
