Code:

mov dx, 0xc004
mov al, 0x20
out dx, al

mov dx, 0xc008

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
http://en.wikipedia.org/wiki/Color_Graphics_Adapter

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:
