Evidence for number of different colour charges

[indie452]

Homework Statement

what experimental evidence is there for the number of different colour charges?
this was on one of our past papers but i don't really understand a few of the answers found online and hyperphysics.com seems to have some of the info missing from the page...

all i know is that the number of colours is related to the ratio of the number of hadron events to the number of muon events, this somehow points to 6 quarks and 3 colours but i don't know why or how...


thanks for any help

Yes, I'd like to know the answer, too.

Anyone? ​
