General Aspects of Pigment
A chemical compounds called pigments reflect light in the visible part
of the spectrum. The chromophore is a highly delocalized component in a
molecule that is frequently responsible for absorbing light in the
visible area and giving the compound a colourful appearance, is what
causes the colour to be created. Carbon-carbon double bonds, benzene
rings, carbon-oxygen double bonds, lone pairs of nitrogen or oxygen and
other forms of groups may all play a role in the delocalization. An
electron’s energy and excitement are captured by this structure and
transferred to an upper orbital. The unabsorbed energy is reflected
and/or refracted in order to be captured by the eye. The eye then
converts this energy into neural impulses, which the brain interprets as
colour (Silva et al., 2021).
