PERENNIAL (photo-thermal)

I took it outside on a chilly morning and watched it turn from pale to almost neon—the temperature sensitivity is surprisingly fast. Definitely not what I expected from a polish, but in a good way.

The color shift is wild—inside my dim office it’s a deep cold tone, but stepping onto the porch for two minutes under direct sun it warms up noticeably. I’ve tested it on a cloudy day versus a bright one and the temperature change really does alter the shade, which makes it feel like two polishes in

Took this polish on a chilly morning walk and the deep blue-purple tone that appeared when I stepped into direct sun was honestly mesmerizing. The cold-state color is subtle enough for everyday wear, but the shift is dramatic enough to get compliments.
