Here is a method besed on CIE1931 system: NfR, m]
'[Oi_gE.
1) Try to find the intersection point of CIE1931 standrad curve and the following line: g,y`[dr
y=k*(x-0.3333) + 0.3333 =oT@h
9VI
here ~uC4>+dk
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. yc]ni.Hz
Q(k$HP
2) the wavelength of the intersection point will be the dominant wave to be determined. 8)"KPr63M

If you need further help, I can share an Excel file. J~gfMp.
