Hi, r2=4Wx4(

Here is a method besed on CIE1931 system: (%)<jg1
Cznp(z
1) Try to find the intersection point of CIE1931 standrad curve and the following line: 78kT}kgW
y=k*(x-0.3333) + 0.3333 m^KK
#Hw/`
here #\&64
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. &5n0J

2) the wavelength of the intersection point will be the dominant wave to be determined. 8B;HMD
