Hi, K/*"U*9Kv
/V`SJ"
Here is a method besed on CIE1931 system: e8wPEDN*4
E
i>GhvRM
1) Try to find the intersection point of CIE1931 standrad curve and the following line: X%&7-PO
y=k*(x-0.3333) + 0.3333 {fHY[8su0
here x-ue1
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. GG<0k\RN
2kDv
(".
2) the wavelength of the intersection point will be the dominant wave to be determined. <y~Ba@1u
+F8K%.Q_
If you need further help, I can share an Excel file. njZ vi}m~
