Psychtoolbox

Psychtoolbox:PsychColorimetric.

Colorimetric and spectral calculations. See also Psychtoolbox:PsychColorimetricData.
And also see the closely related Psychtoolbox:PsychRadiometric. Sometimes it is
not entirely clear whether a routine should be classified as colorimetric or
radiometric. Apologies if our intuitions don't match yours
