Blue color is everlastingly appointed by the Deity to be a source of delight.

Ruskin treats color not as a neutral physical fact but as part of a morally and spiritually charged natural order. The sentence suggests that blue—associated with sky, distance, and atmosphere—has a peculiar capacity to give pleasure, and that this pleasure is not accidental but built into creation. In Ruskin’s aesthetic theory, delight in nature’s beauty is intertwined with reverence: to perceive color rightly is to acknowledge a providential harmony between the world and human feeling. The claim also reflects his resistance to purely mechanistic accounts of perception, insisting that beauty has purpose and meaning beyond optics.
