There is often confusion about this. Recital will certainly carry the dark blue silks as he is a Group 1 winner, while PM is a Group 2 winner. This does not mean that Recital is preferred, however, and those that take it as a sign of such are misled.
Memphis Tennessee will probably carry Magnier’s second colours (pink).
Magnier, Tabor and Smith of course each have a set of first colours. They will continue to wear the colours they are usually seen in according to the precise ownership structure in each of them (no preference is indicated by any of the sets of first colours over another set of first colours). So Treasure Beach will carry Smith’s first colours and Seville Tabor’s first colours.
I believe there are slight differences to Magnier’s first colours that are worn in France, so Pour Mour will wear those (similar to Recital’s). In other words you won’t be able to tell very much from who wears what.
The only thing you will know from the colours is that Recital is wearing Magnier’s first colours and Memphis Tennessee the second, but this is simply by virtue of Recital being a Group 1 winner.
