A colored glass has a formula of R′20—RO—SiO2, wherein R′ is an alkali metal element and R is an alkaline earth metal element. The colored glass comprises between 0.01 and 1% by weight of molybdenum expressed as MoO3 and between 0.01 and 2.5% by weight of sulfur expressed as SO3. The colored glass further comprises between 7.8 and 14% by weight of potassium expressed as K2O and between 0.68 and 5.42% by weight of sodium expressed as Na2O. The sum of the concentrations of potassium and sodium expressed as K2O and Na2O is between 11 and 17% by weight.

The present invention relates to a light-transmitting substrate (1) which is at least provided with a light-absorbing coating (3). The light-absorbing coating comprises stabilized pigments which are incorporated in a sol-gel matrix. The light absorbing coating comprises silica particles having a size between 5 and 100 nanometers and alumina particles having a size between 5 and 50 nanometers. The total volume concentration of pigments, silica and alumina particles in the light-absorbing coating is between 20 and 65 percent. The volume concentration of silica particles is between 5 and 40 percent and the volume concentration of alumina particles between 1 and 15 percent.
