Here is a method besed on CIE1931 system: 97x%2.\:  
B "n`|;r5  
1) Try to find the intersection point of  CIE1931 standrad curve and the following line: oWrE2U;  
  y=k*(x-0.3333) + 0.3333 +wts 7,3  
   here e-!?[Ujv*%  
   k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. <UAP~RH{  

tJ1-DoU  
2) the wavelength of the intersection point will be the dominant wave to be determined. 4Bo<4
