Color-On-Demand Technology

Color brings vibrancy to life, and the more color your products display, the moreyour sales will be enhanced. At times, presence, formation or disappearance of color is a functional feature of the product. For years now Spectra Group specializes in PHOTOCHROMIC color changes, when color effects are brought on by interaction of light with matter. 



Our additives can be added to the variety of matrices. These additives,as well as fully developed liquid or coated/printed products can provide the variety of colors and duality of change (both formation and disappearance). Light induced color change can happen AFTER the product has taken its final shape or DURING the process. Spectra Group's 'Color On Demand' has a series of fully developed products for sale, however, we are willing to customize for your particular needs and conduct joint Research & Development if needed. Please contact us for test samples, collaborative R&D, or to purchase any of our SPECTRACOLOR product line.
