Hi, zi3\63D3eO
`F>O; >i''
Here is a method besed on CIE1931 system: PV=5UyjW
T'b_W,m~,u
1) Try to find the intersection point of CIE1931 standrad curve and the following line: \~_9G{2?
y=k*(x-0.3333) + 0.3333 @n": w2^B
here )<Hd T
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. (zFi$
_:VB}>
2) the wavelength of the intersection point will be the dominant wave to be determined. -bU oCF0
1&U>,;]*
If you need further help, I can share an Excel file. s4uhsJL V$

Let me know how thing's going. 0/oyf]HR
