The dyes, compositions and methods of the present invention are advantageous in providing improved hueing of fabric, including whitening of white fabric, while avoiding significant build up of bluing dyes on the fabric.

A whitening agent for laundry care compositions comprising a thiazolium dye is selected from (E)-2-((4-((2-hydroxy-3-(2-(2-(2-hydroxyethoxy)ethoxy) ethoxy)propyl)(2-hydroxy-3-(2-(2-hydroxyethoxy)ethoxy)propyl)amino)-2-methylphenyl) diazenyl)-3-methylthiazol-3-ium;
