Hi, L{VnsY V
l$1?@l$j
Here is a method besed on CIE1931 system: -HGRrWS
lusUmFm'*
1) Try to find the intersection point of CIE1931 standrad curve and the following line: Q3%]
y=k*(x-0.3333) + 0.3333 V'#R1 x"3
here 6O,k! y>
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. eH7x>[lH.
bD=H$)
2) the wavelength of the intersection point will be the dominant wave to be determined. sN8pwRj b
eCR^$z=c
If you need further help, I can share an Excel file. =v^#MU{k?
