You ought to love colour

?You ought to love colour, and to think nothing quite beautiful or perfect without it; and if you really do love it, for its own sake, and are not merely desirous to colour because you think painting a finer thing than drawing, there is some chance you may colour well. . . . But to colour well, requires your life. It cannot be done cheaper.?

?John Ruskin, from The Elements of Drawing, 1857.
