Notes
The [0.4254, 0.4044] whitepoint chromaticity coordinates are described by [Woo14] to be that of a “2° Planckian source at 3,200 K”. However, we can show that the chromaticity coordinates should be [0.4234, 0.3990]:
sd = colour.sd_blackbody(3200) colour.XYZ_to_xy( colour.sd_to_XYZ( sd, colour.MSDS_CMFS["CIE 1931 2 Degree Standard Observer"] ) ).round(4)
