One of my favourite colour ways, seen here on our Supersonic hair dryer. I chose the purity of 23.75 karat gold leaf for its colour, lustre and quality. Dyson design engineers and model makers then learned to gild under a master gilder. Beneath the gold leaf is a red loop, which is known to give a warm, rich finish. Once sprayed, two layers of gold leaf from Florence, Italy, are applied by hand and carefully brushed to form a smooth and even finish. The blue lacquer has a silver underneath to give luminosity.
