"We took this material--it's kind of a thick paper--and our challenge was to get this onto a 3D object like our cars," BMW research engineer Stella Clarke told Reuters.

"My favorite use case is the use of color to influence sunlight reflections," Clarke said.

克拉克说：“我最喜欢的用例是使用颜色来影响阳光反射。”

"On a hot, sunny day like today, you could switch the color white to reflect sunlight," she explained.

她解释说：“在像今天这样炎热、阳光明媚的日子里，你可以换成反射阳光的白色。”

"On a cold day, you could switch it to black to absorb the heat."

“在寒冷的日子里，你可以换成吸收热量的黑色。”
