Science Week

Science Week

The lighting and colour research group of the Complutense University of Madrid participated in the science week with the event "Is the color of the objects real?"

¿El color de los objetos es real? | Semana de la Ciencia y la Innovación 2021 (semanacienciamadrid.org)

In this event, different experiments were carried out to test if colour is really real.


Colour depends on three fundamental factors: the pigments that the object is made of, the lighting under which it is illuminated, and the perception of the human eye, as not all humans perceive colour in the same way. 

As shown in the following images, the balls used in the experiment are not perceived with the same colours under white illumination as under red illumination.
