How these matches are scored

30 similar shades scored two ways: the shade match on colour, depth, undertone and colour family; the overall match on shade match, finish and visual result, wear and performance and comfort and suitability. A pair with no swatch colour on one side or Low data confidence is listed without a score. Ingredients are shown for information and used by the filters only. Prices are shown next to every match and never change a score. How scoring and confidence work.

Shade colours are sampled from Beautler’s processing of retailer swatch images and are a digital approximation. Prices and stock were last checked when the product was imported; the retailer page is the source of truth.
