The Mathematical Standard for Foundation Matching

Shade matching infrastructure to reduce returns and grow revenue.

ShadesLab is building the physics-based matching engine that eliminates shade mismatch — the #1 reason for cosmetics returns. No more visual guesswork. Pure mathematics.

Let's Talk

Collaborating with European university optical laboratories to validate the science.

The Science

Shade Matching Was Always a Physics Problem.

For the first time, every foundation shade in the world shares one coordinate system. Brands, retailers, customers — all speaking the same language.

Spectrophotometry

The same instrument used in aerospace. Applied to every shade.

CIELAB Color Space

One universal coordinate system. Every brand speaks the same language.

ΔE₀₀ Formula

The gold standard for color difference. A number, not a guess.

Universal Match API

Physics under the hood. A simple answer for your customer.

Reasoning Layer

The AI Layer That Turns a Match Into a Decision.

Most tools give you a score. We give you the reasoning behind it.

Breaks down every match across Lightness, Temperature, and Undertone

AI agent reasons through the difference — not just measures it

Explains why a shade is a match in plain language

Adapts the reasoning to context — new purchase, cross-brand, or out-of-stock

One clear output: what to buy and why

For Brands

For Retailers

Their Anchor Shade Is Your Biggest Sales Barrier.

Let's Talk

New customer acquisition

A shopper knows their shade in another brand. Show the mathematical equivalent in yours — before they bounce.

Conversion across the entire funnel

Uncertainty kills sales at every stage — not just the first purchase. A match score removes doubt at the moment of decision. Certainty converts where hesitation doesn't.

Repeat purchase & LTV

Right shade on the first try = no return, no frustration, no churn.
