Yeah, Roberts rules for home games seems to support this assumption as well.
Under Section 3 - General Poker Rules - irregularities

So a strict interpretation of the rules in even
@CraigT78 's situation would suggest the money be returned once a card from the wrong deck "appears."
However, since both players are all in and no one is harmed by making action, I think this is another situation covered by the leeway in the original Robert's to make a ruling to put fairness before a strict interpretation of the rules.
Agreed, provided all other cards dealt (live hands, mucked hands, and any previous burn and board cards) are all from the same deck.
I've actually seen a live tournament hand where the initial deal was from red deck, flop from blue deck, and turn from red deck. It was noticed before any action ocurred on the turn. Total chaos ensued.
Two players wanted to a) void the entire hand and return all bets (correct), while most wanted to b) return the flop bets, reshuffle the red cards (stub and burn/turn) and deal a brand new flop. One guy wanted to c) return the flop bets, leave the turn in place, and deal a new flop while resuming action with four board cards showing (he didn't have live cards).
It wasn't my game, and I advocated ruling it a misdeal (I had folded pre-flop). The players with great starting hands didn't want to give them up (I think there were three live players to the flop and turn, two with pocket pairs and one with AKs).
After discussing it, the strongest sentiment at the table seemed to be no misdeal and to use option c to continue the hand. When it became clear to me that no misdeal was ever going to be ruled, I pointed out that the only way to maintain the red deck's correct and intended burn and board cards -- in proper order -- was to use the turn burn card as the flop burn card, and use the turn card with the next two cards in the stub as the new flop.
Several players treated this suggestion like an alien sighting, and trying to explain why option c was actually preventing the intended board cards from appearring was like trying to explain advanced physics to hamsters. Never mind the inherent unfairness of the information now potentially available from the faux-flop betting round -- these guys couldn't get past the perceived strength of their starting hands.
The three players ended up agreeing to proceed with option c anyway. It was my first (and last) appearance at this multi-table tournament, one with no apparent rules, or a designated rule/decision maker, either -- it was all done on a table-by-table basis. That one hand burned up 15 minutes of clock time.
