Well, atleast someone else thought Mace's lightsaber was blue. I can't really remember how it compared to the other blue lightsabers at the theatre but I remember it looking like a regular blue. lol His lightsaber was never blue. Ever. Not even one minute was it blue. Sam Jackson asked for a purple lightsaber when he was cast. Befor principle shooting began. We knew this. It's been common Star Wars knowledge from the beginning.
