Ojer Axonil unable to flip
Had a flipped Ojer Axonil//Temple of Power on the battlefield. Attacked with a token with a Sunfire Torch equipped and sacrificed the torch, dealing my opponent 2 noncombat damage. After combat, I sacrificed 2 artifact tokens to 2 Oni-Cult Anvils to deal them 2 more noncombat damage, all from red sources. Temple of Power states that if red sources you control deal 4 or more noncombat damage in a turn, you can flip back to Ojer Axonil, but I was not allowed to, losing me the game.

Read Sunfire Torch. It says, that the creature is dealing the damage. It was a token as you stated, probably one of of the Oni-Cult Anvil. And those tokens are colorless.
