Hi, dl;^sn0s
gM^ Hs7o,
Here is a method besed on CIE1931 system: }gGcYRT
sMs 0*B-[
1) Try to find the intersection point of CIE1931 standrad curve and the following line: M,3sK!`>
y=k*(x-0.3333) + 0.3333 P9SyQbcK
here [Xg?sdQCI
k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. u\<
