The present invention relates a colored soda-lime glass which comprises iron in a quantity which, expressed in weight of the oxide FeOin relation to the total weight of glass, is greater than or equal to 0.5%, and less than or equal to 1.0 % (quantity of total iron), a ratio of Fe2+/total Fe (redox ratio) in the range of between 20 and 65 % and titanium in a quantity which, expressed in weight of TiOin relation to the total weight of glass, is greater than or equal to 1.0 %. This glass has a light transmission (TLA4) in the range of between 15 and 55 %, a total transmission in the ultraviolet (TUV4) of less than or equal to%, and a dominant wavelength in transmission λD of less than or equal to 491 nm. This glass can be used, for example, as side glazing, rear-view window, roof glazing or opening roof of a motor vehicle.
