“Blue color is everlastingly appointed by the deity to be a source of delight,” said the British art critic, John Ruskin. It’s why the Chinese painted their porcelain with cobalt oxide, why the Peruvians used indigo for dying textiles, and why Yves Klein dedicated his creative life to the pursuit of the perfect blue. There is no colour as universally adored as blue. “Blue has no dimensions. It is beyond dimensions,” said Klein. It is the sky, it is the sea. It is this beautiful piece of sea glass.
