Yes single RGB LEDs could work for each eye and a mouth if you have a tight form factor inside your robot's head, that's good idea.

i was just reading.does the bit have multiple colors?for the mout i have enouch, white ports.its the eyes .

so adres rgb is 0xA2 so next is 0xA3 ?

The blaster bit has all the colors of the Rainbow.

If you wanted to use 3 sets of EZ-Robot RGB Eyes, you could use 0xA0, 0xA2, 0xA4, etc
