Are Republicans red or blue?

Excuse me, could you clarify something for me? I've noticed that there's often a discussion about the colors associated with political parties, specifically Republicans. Now, I'm a bit confused. Are Republicans traditionally represented by the color red, or is it blue? I've seen both used in various contexts, so I'm not entirely sure which one is accurate. Could you please shed some light on this matter for me? It would be greatly appreciated.
