If The Prismatic Piper is your commander, choose a color before the game begins. The Prismatic Piper is the chosen color.
Partner (You can have two commanders if both have partner.)
The Prismatic Piper is a generic vanilla 5/5 (actually 5/5 for 5) whose entire purpose is to let you run a mono-color or off-color partner deck without a 'real' commander. You pick a color before the game, cast Piper as a body when you have nothing better to do, and lean entirely on the 99 to win. Functionally you're playing a normal one- or two-color deck where the commander is essentially a vanilla beater that fills curve and provides Partner flexibility.
Treat the deck like a Constructed mono-color build: invest in premium colorless ramp (Sol Ring, mana rocks) and your color's best tutors, card draw, and finishers since the commander provides none. Add an interaction suite and a focused win package—either a tight combo or a Voltron equipment shell to give the vanilla body relevance. If you want a second color, swap to a strong Partner pairing so the commander actually contributes an ability instead of just a body.
