Quick answer：

Gradient nail designs are a popular trend in the beauty industry, where colors gradually blend from one to another. These designs often start with a darker color at the base and fade into lighter shades towards the tips of the nails. The term '渐变' in Chinese refers to this smooth transition of color, and '显白' could imply a design that enhances the nails' appearance, possibly by using lighter colors that are more suitable for pale skin tones.
