We're told white keeps you cool and black soaks up the heat — but where does purple fit in? Imma Perfetto joins David Boldeman to unpack the surprising physics of colour and heat after a new purple fabric was found to keep you cooler than white cotton. The discovery was made by researchers at Adelaide University.
They discuss why purple absorbs more light than you'd think, how passive radiative cooling works, and what this could mean for beating extreme heat as the planet warms.
