Abstract: A blue external reflection solar glass article comprising a transparent substrate having a first surface provided with a thin multilayer coating comprising a first functional layer based on titanium nitride and a second functional layer based on niobium nitride, each functional layers sandwiched between two dielectric coatings. The thin multilayer coating is characterized in that a ratio of thickness of the first dielectric coating to the second dielectric coating is greater than 1.5 and a sum of the thicknesses of all the dielectric coatings in the thin multilayer coating ranges between 30 nm and 170 nm for achieving blue external reflection color, visible light transmission (TL) ranging between 5% and 65% and a low external reflection value (Rg) without drastically increasing the internal reflection value (Rc).
