I considered blue chequered pattern design, like off Diamond Dust Zone but I thought a blue background might not be too different from the usual background and may cause some confusion. Green and red though, well it is perhaps just me but the squares seems to "shift" to me if you stare at them by some sort of colour optical illusion and don't want that to upset it's viewers.
