Very few people in the world would care to listen to the real defense of their own characters. The real defense, the defense which belongs to the Day of Judgment, would make such damaging admissions, would clear away so many artificial virtues, would tell such tragedies of weakness and failure, that a man would sooner be misunderstood and censured by the world than exposed to that awful and merciless eulogy.
Gilbert K. ChestertonNow, among the heresies that are spoken in this matter is the habit of calling a grey day a "colourless" day. Grey is a colour, and can be a very powerful and pleasing colour.... A grey clouded sky is indeed a canopy between us and the sun; so is a green tree, if it comes to that. But the grey umbrellas differ as much as the green in their style and shape, in their tint and tilt. One day may be grey like steel, and another grey like doveโs plumage. One may seem grey like the deathly frost, and another grey like the smoke of substantial kitchens.
Gilbert K. Chesterton
