Hi, Le?yzf
X:/Y^Xu
Here is a method besed on CIE1931 system: dv7IHUFf
QIb4ghm,
1) Try to find the intersection point of CIE1931 standrad curve and the following line: .dE2,9{Z
y=k*(x-0.3333) + 0.3333 ;$FpxurX
here P}2waJe
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. .a@>1XO
n){F
FM
2) the wavelength of the intersection point will be the dominant wave to be determined. qX_(
M2oLU
+k?0C?/T;
If you need further help, I can share an Excel file. VV%Q "0\
rn8#nQ>QZ%
Let me know how thing's going. =QG0:z)K<v
