Company Profile

Our History

Huizhou Foryou Optical Technology Co., Ltd. (FYOTEC's KalorFeel®), established in 1996, is an enterprise in China to successfully develop and mass-produce Optical Color-Shifting and Chameleon Pigments. For nearly 30 years, we have remained steadfastly focused on the R&D, production, and sales of specialty pigments—including optical color-shifting pigments, magnetic optical color-shifting pigments, and mirror-effect aluminum pigments. Our products are widely utilized across global anti-counterfeiting, cosmetics, automotive coatings, industrial spraying, consumer product packaging, and artistic creation sectors, establishing us as a global leader within the industry.

Headquartered in the Foryou Industrial Park within the Zhongkai High-tech Zone in Huizhou, Guangdong, the company operates a modern production base spanning approximately 4,000 square meters of land area and 25,000 square meters of floor area. With a registered capital of 105 million RMB, the company currently employs a workforce of approximately 260 individuals. This includes a professional R&D team of over 60 members—led by Ph.D. and Master’s degree holders—accounting for more than 23% of the total staff. With an annual production capacity reaching 20 tons, we stand as China’s leading manufacturer of optical color-shifting pigments—ranking domestically and holding a leading production scale globally—and serve as a leading benchmark enterprise within China's optical color-shifting pigment industry.

Recognized as a National High-tech Enterprise and the Guangdong Engineering Technology Research Center for Special Materials and Applications, FYOTEC's KalorFeel® has successfully obtained ISO 9001, ISO 14001, and ISO 45001 management system certifications. Upholding our core mission of "Pioneering Innovation, Quality First, and Serving the Globe," we provide our worldwide clientele with comprehensive, one-stop specialty pigment solutions—ranging from custom color formulation to technical application guidance.

Leveraging cutting-edge Physical Vapor Deposition (PVD) technology, our company presents a revolutionary color solution: KalorFeel® Structural Pigments (also known as FYOTEC's KalorFeel® Optical Color-Shifting Pigments). Breaking through the limitations of traditional pigments, KalorFeel® achieves unparalleled color purity and saturation. These pigments feature vivid hues and a strong metallic luster, delivering unique color effects—characterized by intense visual impact and a shimmering metallic glint—that are simply unattainable with ordinary pigments. Furthermore, the product is eco-friendly, highly stable, and possesses exceptional weather resistance. KalorFeel® Chameleon Pigments will endow your products with stunning coloration, instantly allowing them to radiate with dazzling brilliance.
