Cor luz – cor pigmento: a física e as artes

Abstract

Among different characteristics of human being,
there is the ability to adapt communication with other men.
Through information received by our sense organs, it is
possible to detect the phenomena of nature and to decode
this information according to our own sensibilities. Although
all human beings considered normal physiologically
demonstrate similar generical behaviour, variable factors
named feeling can be verified. And in order to trigger
feelings a stimulus is necessary, and its conversion into
electrical pulse, its conduction to the brain and its driving
Integration of successive pulses. According to historical
aspects, together with physiological characteristics, it
appears that colour, or colours, stimulate and influence the
receptor, causing different reaction. As the variety of
colours is infinite and its limits change according to viewer's
perception, this research included the sense of sight,
specifically the Somatic Sense of Colour, and a physical
study of shades.
