It's... green!
My grandfather once saw a huge green bolide while out hunting one night. It made quite an impression on him (he called it a comet, but I forgave him).
My father saw a bolide explode in mid-flight in the 1950s. He didn't say what color it was that I could remember.
I've seen a few large meteors in my day, but nothing like what they or you saw... yet.
