We're particularly interested in obtaining pricing details for your pigments, both per kilogram and per ton, focusing on the traditional colors: red, yellow, blue, green, orange, and purple. Additionally, we would appreciate if you could provide us with 10 kg samples of the mentioned pigments to evaluate their suitability for our applications.
