# P4 Phosphor # # White phosphor for black & white televisions # # This phosphor presents a clear white appearance that is perceptually similar # to a black and white photograph on highly reflective paper when the viewing # environment is sufficiently dim, and makes D65 look fairly dull and yellowish # in comparison, that said, next to saturated colors the blueish tint becomes # more apparent. This might explain why this white point was abandoned in # favor of the more neutral Illuminant C (and later D65) for color television. # # Medium-short persistence # # DIRECT3D POST-PROCESSING OPTIONS # chroma_mode 1 chroma_a 0.265,0.285 chroma_conversion_gain 0.30,0.59,0.11 chroma_y_gain 1.0,0.0,0.0
