chameleons answer
Writting the numbers in modulo 3 gives,
R G B
1 0 2
easy to check now that no matter what 2 meet the answer is alwasy the same modulo 3 being,
R G B
0 2 1
which is the same as the start up to the names of the colours. In particular to have all the chameleons one colour it would be required for two of the RGB to be equal (and zero), which we can see now is impossible.
