Hi, -8j<`(M' 5

Here is a method besed on CIE1931 system: 9ANC ,+0p
4NY00d/R
1) Try to find the intersection point of CIE1931 standrad curve and the following line: L*;XjacI]
y=k*(x-0.3333) + 0.3333 gmU_# J%~
here KC+C?]~M
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. l>l)m-;O
BXNt@%
2) the wavelength of the intersection point will be the dominant wave to be determined. G#V}9l8 Q

If you need further help, I can share an Excel file. 1b4aY>
