It seems as the your move choices are not limited to the color of the book you are using. I feel the book is pure aesthetic.
So in other words all attacks are open to you and you book will change just based on the attack you are currently using/used last
However when the spell tomes might run out based on the tome color. So you can use up all your thunder tome and keep using a fire tome
Palutena and the Mii Fighters are the only ones with outrageously different custom special moves. The rest of the cast selects from slightly different choices. I guess it is slightly possible that Robin is another character to add to this list, however I think this is extremely unlikely
It seems most probably that:

is The thunder tome, chargable and able to retain charge like samus' neutB


is Arc fire. acts like ness's PKF


is the windy move.


is that dark magic move
