A water-borne latex paint system and a method of formulating a water borne latex paint system having viscosity color stability. The system includes a base paint, at least one associative thickener, a colorant compound, and at least 0.1% dry weight of a block copolymer ABLBA composition. The block copolymer acts as a viscosity stabilizer in the presence of associative thickeners. The A component includes a monomer unit containing a moiety such as an alkyl group, an aryl group or an alkyl aryl group; the B component includes a polyethylene oxide polymer or a polyethylene-polypropylene oxide copolymer; and the L component includes a dianhydride unit or a diisocyanate unit.
