why do people keep betting on red and black like it matters

Whenever I’m at a roulette table, I see folks going hard on red or black, stacking chips like the color wheel’s about to crack. To me it feels like flipping a coin, since each spin just resets everything - last seven were black, who cares? That doesn’t change the odds this spin, right? I get that even money bets look simple, but I’m not seeing where the “edge” is besides maybe riding a hot or cold streak for adrenaline.

Does anyone here actually have a reason for sticking to red or black, or is it just habit?
