A relationship between zero‐grayness luminance by Evans and perceived brightness of spectrum colors

Abstract: An important finding in the present study is that ''zero-grayness luminance'' proposed by Evans gives approximately the same perceived brightness for spectrum colors irrespective of hues. The luminance values with the same perceived brightness for spectrum colors are directly derived on the basis of VCC method proposed by the senior author. It corresponds to the spectral luminosity function V b2 (k;VCC). In the study process, we had some doubts on the luminosity function CIE V b2 (k) on the heterochromatic bri… Show more

“…L*(H) corresponds to the zero-grayness point at each hue according to Evans. 15,16,23 The above equation represents the fact that a high metric lightness L*(H) is needed to cancel the blackness and obtain the perceived lightness L Ã eq for hues with weak chromatic strength such as the yellow hue. For hues with strong chromatic strength such as blue and purple hues, low metric lightness is enough to cancel the same amount of blackness.…”
