Montana Colors is an Italian company that manufactures and distributes paints, varnishes, lacquers, and other products for the decoration of surfaces.
The company was founded in 1951 by Angelo Montana in the town of Parma, Italy. It grew steadily over the years, but really took off in 1973 when it introduced its first water-based paint. In 1979, it was acquired by a French chemical company and became a wholly owned subsidiary. The company has since been sold to American investors who have been actively expanding the brand worldwide.
Montana Colors is now present in more than 100 countries with a workforce of more than 2200 people.
