Long-lasting, cheap and environmentally friendly paints could be on the way after scientists manufacture unique colour cells from butterflies for the first time.
The paints could be used to make cars that stay shiny forever, make-up that never fades and clothes that never lose their colour.
The vibrant colours you see in a butterfly’s wings are the result of a phenomenon known as structural colouration. Their wings are made up of transparent scales that have intricate shapes. The scales scatter light when it hits them, creating brilliant colours that look different from different angles.
