A glass article including at least about 40 mol % SiOand, optionally, a colorant imparting a preselected color is disclosed. In general, the glass includes, in mol %, from about 40-70 SiO, 0-25 AlO, 0-10 BO; 5-35 NaO, 0-2.5 KO, 0-8.5 MgO, 0-2 ZnO, 0-10% POand 0-1.5 CaO. As a result of ion exchange, the glass includes a compressive stress (&#x3c3;) at at least one surface and, optionally, a color. In one method, communicating a colored glass with an ion exchange bath imparts &#x3c3;while in another; communicating imparts &#x3c3;and a preselected color.
