Same here in the US, though I’ll say as someone actually colorblind, it’s not the easiest to decipher the red/yellow when at speed until you’re somewhat close. Normally not an issue since anything resembling red=start slowing down, but there are situations where a standard light may start acting as a single flashing red or yellow, and that can be tough to figure out at speed. Flashing reds are supposed to have stops signs here as far as I know, but there’s been at least one intersection that hasn’t had them, which certainly gives me some anxiety about taking that as a rule. The system works alright enough, but it’s definitely frustrating that we settled on red/green for things when that’s the most common color blindness. I have some strong opinions on bathroom indicators, particularly in airport bathrooms where the lighting is often sub par too
