X is not less than .350.
Y is not greater than .470.
Y - Y0 or Y0 - Y is not numerically greater than 0.03X.
(Y0 is the Y coordinate of the Planckian radiator for a given X).
1/ The chromaticities of the diffusing lenses or colored filters expressed as
X and Y coordinates on the CIE chromaticity diagram shall lie within areas
bounded by the coordinates listed for each color, using a source illuminate
of 2200° K.
2/ SL = spectrum locus (where intersected by other of coordinate pair).
