Secret color code
Thank you for a charming issue on neutrinos (May 2005). The use of jelly beans of different colors to convey the notion of the various flavors of neutrino is very sweet and engaging.
I am curious about the actual choice of colors. Is there a message in the fact that yellow and pale blue are two of the three subtractive primary colors, producing green when combined in equal proportions? Is this the secret of oscillations, or related to the possible Majorana nature of neutrinos, or merely an indication of your favorite flavors of jelly bean?
