Hi, 5'wFZ=>vMt

Here is a method besed on CIE1931 system: TD!c+${w
PL3oV<\4s>
1) Try to find the intersection point of CIE1931 standrad curve and the following line: pWoeF=+y]W
y=k*(x-0.3333) + 0.3333 @]V_%,
here X#MC|Fzy@
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. _znn `_N:v
0o
8V8 :
2) the wavelength of the intersection point will be the dominant wave to be determined. !]z4'* )W
WBD"d<>'
If you need further help, I can share an Excel file. Ff[GR$m

Let me know how thing's going. E@Yq2FBpnn
