Hi, zEA{%)W
r!-L`GUm
Here is a method besed on CIE1931 system: }lrfO_
J~nJpUyP*
1) Try to find the intersection point of CIE1931 standrad curve and the following line: p~k`Z^xY$
y=k*(x-0.3333) + 0.3333 k;AV;KWI'
here #I*ht0++
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. s\n,Z?m
T3B|r<>I
2) the wavelength of the intersection point will be the dominant wave to be determined. z}Mb4{d1
V2<k0@y
If you need further help, I can share an Excel file. ta+"lM7A}$

Let me know how thing's going. PN)TX~}
