black and white are not extremes of any universe. white is not the opposite of black, nor this one is the adversary of the other. white is not the melted sum of all colours. black is not the annihilation of all colours. there are no nuances, no gradations nor scales between black and white because black and white are colours, different from each other, as ochre is to magenta, and tile sienna to forest earth tone, and glowing cherry red to rat grey, and lichen dry yellow to blue of the impossible, and sanguina to turquoise.
