How to plot "Adobe RGB (1998)" color gamut?

Hi,

I cannot draw Adobe RGB 1998 gamut using this command:

colour.plotting.plot_RGB_colourspaces_in_chromaticity_diagram_CIE1931(
    colourspaces=["Adobe RGB (1998)"], 
    standalone=False, title=None)

For other colour spaces, it’s normal, but not this one. Why is that?

Thanks

It not that the colourspace is designed to have such primaries in the first place, it is more a direct consequence of fitting the camera data to the CIE 1931 2 Degree Standard Observer: if you compute the by-product primaries from the 3x3 matrix mapping the former to the latter, you might get some that goes way beyond the spectral locus. This is actually quite typical from cameras because they are not really colorimetric.

Yeah this is supported so that you can both filter existing RGB Colourspaces while passing a custom one you have just built!

I do it here for example with the Venice colourspaces: https://colab.research.google.com/drive/1ZGTij7jT8eZRMPUkyWlv_x5ix5Q5twMB
