Is white really the coolest colour to wear?

Seems like an obvious scientific and technological evolution that I think we're going to need, Emma.

So just have you rethinking your fashion choices now and thinking, oh, goodness, I better get better at wearing purple in the next 10, 20 years, Emma, or what?

I already wear a lot of purple.

I'll be real with you.

I

think it's 50, 100 years away.

Oh, I don't have the context to be able to give you a timeline.

I think that there's still a lot to be done.

The The samples that they were testing in this study were five centimetre by five centimetre squares.

Those are the scales that we're talking about here.

It is really a proof of concept.

To mass produce it, we're looking at a fair amount of R&D.

Exactly, exactly.

What this is telling us is that it is possible to make passive radiative cooling fabrics that are coloured.

It doesn't have to be bright, brilliant white reflecting all of the wavelengths of light because...

I don't know about you, but I like to wear clothes with colour on them.

I wouldn't prefer to be in a monochrome head-to-toe white outfit every day, every hot.

You do?

I'm wearing a white T-shirt right now for the benefit of those on audio only.

I don't mind it, but I could see the point.

I don't.

I own a purple shirt or two.

I'm a

colour-forward person.
