Hello to all meteor observers !

On this website, it's written : "According to the observed brightness and color, it's a meteoritical rocky body ( probably chondrite )". I was thus wondering if we could determine the type of the object at the origin of the meteor just by analysing its brightness and color. I can understand that those parameters help to make the difference between a reentry and a meteor, but are they also useful to guess what type of meteoroid was at the origin of the meteor ? I thought that the colors of meteors hadn't yet found a clear explanation...
Can someone explain me ?

Thanks in advance !

Clear skies to all !
Karl
