Abstract : A modified Howard-Dohlman type apparatus was used to quantify the ability of 12 observers to adjust the relative distance of grey, red and blue rods under six relative luminance combinations (left or right rod having equal, one-half, or one-quarter the luminance of its comparison rod). The observers perceived the red rod as nearer than the blue under all conditions, with no significant effect of luminance under any condition. It was concluded that color per se is a cue for depth.
