Shade aura

Meet the spectral gradient that powers your perfect match.

Tristim samples your skin in L*a*b* space and projects the results onto our shade aura—an adaptive gradient that calibrates undertone, overtones, and luminosity in real time. It’s how we turn color science into something you can feel.
