different colors is behaveing differently in the same medium. The reson they
have choosen the color they have is that that color is tranfered with the least
loss at an affordable price of the light generator.
To have differnt colors in the same fibre would raise a lot of problems. one is
the transmitting device. blue is very hard and expensive to make for example.
another one is the resciver. As for now, you only have to detect light or no
light. That is MUCH easier than detect different colors.
something close to your idea is actually used in modern modems, that send
several bits per baud, by modulateing both phase and amplitude.
as for today, your technique would be far to expensive and bulky. apart from the
problem with different signal loss of the different colors.
maybe in the future.
