On the Beauty of Flame - Plotinus: AD 204-270, Ennead I.6 / Translated by Stephen MacKenna
The beauty of colour is also the outcome of a unification: it derives from shape, from the conquest of the darkness inherent in Matter by the pouring-in of light, the unembodied, which is a Rational-Principle and an Ideal-Form.
Hence it is that Fire itself is splendid beyond all material bodies, holding the rank of Ideal-Principle to the other elements, making ever upwards, the subtlest and sprightliest of all bodies, as very near to the unembodied; itself alone admitting no other, all the others penetrated by it: for they take warmth but this is never cold; it has colour primally; they receive the Form of colour from it: hence the splendour of its light, the splendour that belongs to the Idea. And all that has resisted and is but uncertainly held by its light remains outside of beauty, as not having absorbed the plenitude of the Form of colour.
