How to get the chromaticity coordinates of an illuminant?

[disidrosi]

I am trying to calculate the CIE x and y values for 2° or 10° of a given illuminant (for example D65 or A).

I am sure there is some easy way to do this. I have found colour.plotting.diagrams.plot_sds_in_chromaticity_diagram, which seems to already implement the conversion, but I can't seem to figure out how to do just the conversion alone.

I also tried:

D65_illuminant = color.SDS_ILLUMINANTS["D65"]
two_degree_cmfs = color.MSDS_CMFS["CIE 1931 2 Degree Standard Observer"]
D65_XYZ = color.sd_to_XYZ(D65_illuminant, two_degree_cmfs, D65_illuminant)
D65_xy = color.XYZ_to_xy(D65_XYZ)

which returns array([ 0.29283577, 0.32305116]). Am I missing something here?

Nevermind, shortly after posting my question I found the solution by using colour.CCS_ILLUMINANTS. For example:

color.CCS_ILLUMINANTS['CIE 1931 2 Degree Standard Observer']['D65']

which returns array([ 0.3127, 0.329 ]).

Glad you found out!
