142 A Painter's Views It is also true that, as with money, more is made by saving than in any other way, and the surest way to lose colour is to play with it inconsiderately, not knowing how to leave well alone. A touch of pleasing colour should on no account be stirred without consideration. That we can see in a natural object more colour than strikes us at a glance, if we look for it attentively, will not be denied by any who have tried to look for it. Thus, take a dull, dead, level, grimy old London wall: at a first glance we can see no colour in it, nothing but a more or less purplish mass, got, perhaps as nearly as in any other way, by a tint mixed with black, Indian red and white. If, however, we look for colour in this, we shall find here and there a broken brick with a small surface of brilliant crimson, hard by there will be another with a warm orange hue perceivable through the grime by one who is on the look out for it, but by no one else. Then there may be bits of old advertisement of which here and there a gaily coloured fragment may remain, or a rusty iron hook or a bit of bright green moss ; few indeed are the old walls, even in the grimiest parts of London, on which no redeeming bits of colour can be found by those who are practised in looking for them. To like colour, to wish to find it, and thus to have got naturally into a habit of looking for it, this alone will enable a man to see colour and to make a note of it when he has seen it, and this alone will lead him towards a pleasing and natural scheme of colour in his work. Good colour can never be got by putting down colour which is not seen ; at any rate only a master who has long served accuracy can venture on occasional inaccuracy— telling a lie, knowing it to be a lie, and as, se non vera, ben trovata. The grown man in his art may do this, and indeed is not a man at all unless he knows how to do it daily and hourly without departure from the truth even in his boldest lie ; but the child in art must stick to what he sees. If he looks harder he will see more, and may put more, but till he sees it without being in any doubt about it, he must not put it. There is no such sure way of corrupting one's colour sense as the habitual practice of putting down colour which one does not see; this and the neglecting to look for it are equal faults. The first error leads to melodramatic vulgarity, the other to torpid dullness, and it is hard to say which is worse.
