Olde World Pigments™ are specially formulated, high pH colorants, which make them eminently suited for use with lime-based products. These concentrated pigments provide coloring strength and disperse easily. Unlike universal tints, which may adversely change color, or regular water based tints that may fade over time, Olde World Pigments remain true and vibrant. Available in 11 Old World colors, they are the best choice for producing gorgeous natural coloration in a wide variety of lime-based materials.
