    Abstract: A colored glass article may include 50-80 mol % SiO2; 7-20 mol % Al2O3; 1-35 mol % R2O, wherein R2O comprises at least one of Li2O, Na2O, and K2O; 1×10−6-10 mol % of a colorant, wherein the colorant comprises at least one of Cr2O3, Au, Ag, CuO, NiO, Co3O4, TiO2, CeO2; and 12-24 mol % of Al2O3+MgO+CaO+ZnO. The colored glass article may have a transmittance color coordinate in the CIELAB color space with an L*value of 55 to 96.5. The colored glass article may have a compressive stress profile with a depth of compression ≥0.15t a thickness t from 0.4 mm-5 mm, a compressive stress ≥200 MPa, and a central tension ≥60 MPa. The colored glass article may have a dielectric constant from 5.6 to 6.4 over the frequency range from 10 GHz to 60 GHz.
