Yeah Leia had a red blade, I remember that. In the old comics there was a villain with a blue saber with two blades as well. Purple, blue and yellow were all used by bad guys in Dark Forces II.
In the 1998 Extended Universe Line, Dark Empire Luke and Leia both had red lightsabers. Clone Emperor had blue.
I used to use the yellow saber that came with Plo Koon to give Kyle Katarn Yun’s Saber.
