I don't think your Reply #6 has added any clarification beyond telling us that you want to send RGB data and you only need 2-way communication occasionally when you are changing settings for a slave.
You have also added the significant complication that you might want to send 60 messages per second.
The simplest way to send data is to have all the slaves listening on the same address and then the master just sends all the data to all the slaves. That just requires 30 or 60 messages per second which is well within the capacity of an nRF24. However you will have to disable acknowledgements and just trust that the system is reliable.
Suppose there is 18 bytes of colour data then you could actually send a slightly longer message to all the slaves with (say) another byte that can indicate to the slave that it should change its behaviour and switch to configuration mode in which it listens on a different address and activates the autoAck process. When you have finished the configuration you could send a message to a slave to tell it to go back to the standard "listen-for-colour" mode.
