unklerhaukus · Answer

730 nm is red .
and i cant find magenta on the spectrum

jamesj · Answer

I'm saying you decide what color is closest to your concept of magenta on the spectrum, and say that's he wavelength.  

But you might be asking a different question: is there some sort of standard definition of magenta?  Then the best thing to do is use a Pantone color: Pantone has a large number of standardized colors.
