== The data ==
Each sprite has the ability to show can display 15 distinct colours, the pixel colours are indexed #0 - #F.
Index #0 is always transparency, whereas index #1 - #F is the colour index in the sprite palette.
== The colour palette ==
The ASIC can handle 4096(16x16x16) colours. Each colour is defined as values of '''red''', '''green''' and '''blue'''.
Each value is handled as 4bit values.
The hardware code send to the ASIC is #0grb.
In the below example changing the palette index colour 1 to value #0F00 gives a '''green''' Pac sprite.

changing the palette index colour 1 to value #00F0 gives a '''red''' Pac sprite.

and finally changing the palette index colour 1 to value #000F gives a '''blue''' Pac sprite.
