*Color region stay within MacAdam "3-step" ellipse from the chromaticity center.

*The chromaticity center refers to ANSI C78.377:2008.

Please refer to ANSI C78.377 for the chromaticity center.

*θ is the angle between the major axis of the ellipse and the x-axis,

and a and b are the major and minor semi-axes of an ellipse. (Ref. IEC 60081:1997 AnnexD)
