Is OU red or maroon?

Excuse me, could you please clarify something for me? I've been wondering about the color of OU. Is it a deep, rich red, akin to that of a ruby or a poppy? Or is it perhaps more of a maroon shade, with a hint of purple or brown mixed in? I'm trying to get a clear understanding of the hue in question, and I'd greatly appreciate your input. Thank you in advance for your help.
