Color by Wavelength in Wolfram Mathematica: Easy Guide & Tips

[Vrbic]

Hello,
I'm wonder if is possible in Wolfram Mathematica to fill some object or just set a color of object by a entering a wavelength, i.e. I write 450 and the line will be blue etc. Please advise me, I didn't find anything useful.
Thank you all.

What you can do is to try and find an algorithm to convert a wavelength to a RGB value.

Ok, thank you. This possibility I took as a last one. I hoped there exists some special function on it. I found this http://reference.wolfram.com/language/guide/ColorSchemes.html , but honestly I don't know what is it for, or how use this "VisibleSpectrum". If there is no other way I will transform wavelength to RGB but it also won't be ease...I guess :-)

The example code for using VisibleSpectrum is at http://demonstrations.wolfram.com/s...ength&demodisplayname=Color versus Wavelength. The example converts the wavelength to r,g,b numbers and uses them.
