White: This is the spiritual color of our times, the clearness which directs all our actions. It is neither grey nor ivory white, but pure white.
White This is the color of modern times, the color which dissipates a whole era; our era is one of perfection, purity and certitude.
White It includes everything. We have superseded both the 'brown' of decadence and classicism and the 'blue' of divisionism, the cult of the blue sky, the gods with green beards and the spectrum.
White pure white...
