Rolfes is a well-established name in South Africa and internationally. The business dates back to 1925 when the Rolfes family commenced business. The family initiated the manufacturing of lead and chrome containing inorganic pigments in South Africa and by 1970, started producing organic pigments.

New investors, under new management with a vision for renewal and growth acquired the business in 1999 and the current Rolfes Group was born. The renewal and turnaround activities, brand building, and strategic acquisitions followed.

The company concluded a successful BEE transaction with Vuwa Investments and was listed on AltX during 2007. The company's listing was transferred to the Main Board of the JSE on 21 November 2011.
