Modern paints using adhesion additives have allowed a wide range of standard paint colours to be applied to glass. Typically, they are called and used as “splashbacks” but have a wide range of uses, normally internal.
In most cases they are toughened for safety and to comply with gas appliance standards and the paint is normally applied to low iron glass to achieve exact colour matching.
Size limits apply according to the manufacturer and care is required with the glazing and sealing methods.
