MacAdam ellipses and determination of tolerance and chromaticity changes of light emitted by lamps
A MacAdam ellipsis is a region on a chromaticity diagram which contains all colors which are indistinguishable to the average human eye from the color at the center of the ellipse. The contours of the ellipse represent the just noticeable differences of chromaticity. MacAdam ellipses help to show differences of chromaticity between two light sources [...]
