Cobalt titanate green is a modern inorganic pigment known for its stability, durability, and distinctive muted green hue. Developed in the mid-20th century, it belongs to the family of mixed-metal oxide pigments created to offer artists and industry a safer, more lightfast alternative to earlier, less stable greens. Its colour is achieved through a solid–state reaction between cobalt and titanium oxides, producing a spinel-type structure that resists fading, heat, and chemical alteration.

In art, cobalt titanate green is valued for its excellent covering power, matte finish, and ability to maintain chromatic consistency under a wide range of lighting conditions. It has been widely adopted in contemporary painting, restoration work, and industrial coatings, especially where long-term stability is essential. Its non-toxic nature and compatibility with various binders make it a reliable choice for artists seeking a permanent, environmentally safer green with subtle, naturalistic tones.
