Hi, ura&9~
s-rc0:I
Here is a method besed on CIE1931 system: f DXK<v)
v,}C~L3
1) Try to find the intersection point of CIE1931 standrad curve and the following line: /FN:yCf
y=k*(x-0.3333) + 0.3333 @HbRfD/!
here GPHb-
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. >`03EsU
*}89.kCBF
2) the wavelength of the intersection point will be the dominant wave to be determined. LKvX~68

If you need further help, I can share an Excel file. R7Qj<,

Let me know how thing's going. E9\"@wu[d
