Abstract	Chromatic blur seen along the contours of a figure on a color TV display is not so annoying if the contour luminance signal is sharp. This is due to the human visual property that chromatic blur is masked by the luminance by spatial luminance changes. This paper describes the subjective evaluation of the visual masking effect of chromatic blur depending on luminance signals. From the experiments, the chromatic blur becomes less perceptible with the increase in level of superposed luminance signals and the blur is more annoying in red than in blue or yellow. Highly saturated red figures cause poor picture quality.
