Abstract: A method of forming a multi-colored glass substrate comprises: irradiating a first region of a glass substrate with a first high energy source to form a first irradiated glass substrate; and subjecting the irradiated glass substrate to a first heat treatment to form a first heat treated glass substrate, wherein the first heat treated glass substrate comprises a second region having a different transmittance color coordinate in the CIELAB color space, as measured at an article thickness of 1.33 mm under F2 illumination and a 10° standard observer angle, than the first region.
