Abstract

Fechner colors are visible when two black and white photographs of a scene which have been taken with longwavelength and short-wavelength light, respectively, are viewed in an alternating sequence. Such colors may be combined with spatially induced, two-primary colors to enhance or reduce the vividness of the latter.
