Dithering more offers a good "texture" or feel effect than real "new colours".
Few games on CPC werein fact C64 ports (graphically, indeed) as the C64 did had such video mode as the Amstrad's Mode 0...
But Hardware Sprites capabalities were even more used... Also because the C64 did had less coloured palette,n and a lot of grey... the graphical results were quite different.
Notable games editor who used well the Mode 0 capabilities was the Spanish [[Dinamic]] corporation...
They often used latinos Comics stars illustrations as intro pictures.
Yet the games area was often smaller than average...
