i think they are 16 of them, and upper byte means background colour, and lower byte means forecolour (textcolour), but i am not sure
they are probably chosen from a palette of 16 colours

Try the following link

0x20 means black text on green background
0x08 means gray text on black background

No, Vid, sorry, I don't know anything about 64 BIT ega color, but I do know something about 64 COLOR EGA. Here's a reference from Charles Petzold, describing the first version of windows, version 1.0:
