White (n.) is lighter than black, not by its essence or constitution, but because one sample serves as the paradigm of both white and lighter.
White (n.) is whatever we call the lighter colour, which is why light is white sounds so evident: lightness and light are equated.
White (n.) is the lightest colour on the palette, yet in a picture the blue sky can be lighter than white paper, as Goethe noted.
White (n.) applies rightly to paper in its normal setting even if snow beside it makes it look grey; a laboratory may need a finer concept.
White (n.) and grey can be the same colour in different senses: white in poor light here, grey in good light there.
White (n.) as a substance colour is the lightest, colour being a darkening, so with all darkening removed white is left and may be called colourless.
White (n.) blended in removes colouredness from a colour, which yellow blended in does not; here phenomenology tempts as midway between science and logic.
White (n.) is not a blend of colours as lilac is reddish-whitish-blue, and Newton did not prove that it is.
White (n.) is not essentially a surface property, since it can appear as a highlight or the colour of a flame.
White (n.) sometimes stands level with pure colours, as in flags, sometimes not; that we draw a sharp line here makes it a conceptual matter.
