山顶保温杯的冷热对比

An unbranded brushed steel thermos cup is placed on a flat rock on the top of a mountain in the early morning. There is a small amount of heat in the cup lid, and the grass tips are frosted in the background. The edge of the product is clear, and the cold blue environment forms a restrained contrast with the heat at the mouth of the cup.
