Sennelier Rive Gauche Fine Oil Colors. Designed to dry faster and resist yellowing better, Sennelier Rive Gauche Oil Colors are a great addition to your palette. The Rive Gauche formula boasts a quicker drying time than classic oil brands, making them a good choice when painting multiple layers. While another Titanium White may take more than a week to dry, Rive Gauche dries in as little as five days — almost twice as fast! And because they're made with safflower oil, these oil paints are less prone to yellowing than brands made with linseed oil. Rive Gauche Oil Colors have a high pigment concentration, which allows for strong covering power and cleaner mixes.
