When the streets are paved with brilliants and the skies made of rainbows I suppose you'll be contented and satisfied with red, blue and yellow.... how to satisfy your tawdry friends while you steal back into the mild evening gleam and quiet middle term[? ]. I'll tell you, my sprightly genius, how this is to be done. Maintain all your lights, but spare the poor abused colours till the eye rests and recovers. Keep up your music by supplying the place of noise by more sound, more harmony and more tune, and split that cursed fife and drum.... he [Mr. Garrick] must feel the truth of what I am now saying, that neither our plays, paintings or music are any longer real works of invention, but the abuse of Nature's lights and what has been already invented in former times.
