Hi, lk80#( :Z

Here is a method besed on CIE1931 system: Uoix
3irl
(;v
1) Try to find the intersection point of CIE1931 standrad curve and the following line: )BfAw
y=k*(x-0.3333) + 0.3333 /2VJX@h
here 2I{"XB
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. <QGXy=
h!9ei6
2) the wavelength of the intersection point will be the dominant wave to be determined. Srd4))2/0

If you need further help, I can share an Excel file. |(^PS8wG

Let me know how thing's going. IO:G1;[/2L
