When the Google Home Mini debuted last year, it was available in a dark "Charcoal" grey, a lighter "Chalk" grey and a pinkish orange "Coral." Today, a week before Google's annual Pixel event, the company is unveiling a brand new hue of the Home Mini -- a minty blue "Aqua." "Coral is warm, Aqua is cool," said Isabelle Olsson, the head of industrial design for Google Home, to Engadget. "It's a soothing yet fresh option that could be used to either contrast or blend in." Google's Home Mini is undoubtedly one of the company's best selling products.
