Abstract
We investigated the ability to recognize the
color of surfaces in fish (Poecilia reticulata),
bred from birth in conditions of artificial light
with constant spectral content. The capacity for
color constancy significantly deteriorated when
compared that to the control group. Further
alteration of lighting conditions and transfer
into natural daylight conditions restored the
suppressed function to its normal level. We
suggest that the color constancy function
belongs in the visual system-response functions,
the full development of which requires the
accumulation of individual visual experience.
