Both red and black bets offer identical odds and payouts in roulette. In American roulette, it's slightly reduced to 47.4%. Due to these relatively high chances, these bets are very popular among players. The payout ratio is 1:1, which, although lower than that of straight-up bets, allows for the use of various roulette strategies.
So, choosing between red or black doesn't impact your odds or payouts—they're exactly the same. Additionally, players can also place other even-money bets that offer the same odds and payouts. These include betting on even/odd or high/low numbers.
