A cosmetic foundation composition is provided comprising greater than or equal to 6% by weight of the cosmetic foundation composition of metal oxide particles and having a .DELTA.LT value greater than or equal to 0.5, preferably greater than or equal to 1.5, more preferably greater than or equal to 2.5, where .DELTA.LT is measured according to the following equation: : .DELTA.LT = .DELTA.L2 - .DELTA.L1 . Where: .DELTA.L1 = L1110 L115 ; .DELTA.L2 = L2110 - L215 . L1 is a measurement of Ly taken on bare skin, to which no product has been applied; L2 is a measurement of Ly taken on skin, to which product has been applied; and Ly is the luminosity value at a specific angle, y, from specular.

L'invention concerne une composition de fond de teint, qui renferme, en poids, 6 % ou plus de particules d'oxyde métallique, ayant une valeur .LAMBDA.L<SB>T</SB> supérieure ou égale à 0,5, de préférence encore supérieure ou égale à 1.5, et de préférence encore supérieure ou égale à 2,5, sachant que l'on mesure ?L<SB>T</SB> selon l'équation ci-après: ?L<SB>T </SB>= ?L¿2 ?- ?L¿1?, avec: ?L¿1? = L¿1??110¿ L¿1??15¿; ?L¿2?? ¿= L¿2??110 ¿- L¿2??15 ¿. L¿1? est une mesure de L?y¿ sur la peau nue, sur laquelle aucun produit n'a été appliqué; L¿2? est une mesure de L?y¿ sur la peau, avec application de produit; et L?y¿ est la valeur de luminosité à un angle spécifique, y, en éclairage spéculaire.
