Tests were done on the human eye for standards to be set for
color television phosphors bye the CIE (France) and the ICI
(US) International Commission of Illumination. The CIE is
recommended as standards by the Standards committee of the
Institute of Electrical and Electronics Engineers.

Results.

From the Wald and Brown (1965) experiments the three peak
sensitivies of the cones (color sensors are 450, 530 and 570
nanometers.

The CIE primaries are 
Red:    700 nm
Green:  546.1 nm
Blue:   435.8 nm
  
The FCC phosphor Wavelengths are

Red:	610 nm
Green:	535 nm
Blue:	460 nm

I believe that each film in cameras had different pigments
and there is no standard set in stone. However of that I am
not sure.

I hope this is of some help.
