3-3/4'' Cat figurine in Cobalt Cobalt, a decorating favorite, returns for Christmas 2010 with this 3-3/4'' Cat figurine. There are more than 60 different Blues in the Fenton product line. Cobalt creates a dark blue and copper imparts a light blue. In combination with each other or with additional coloring agents, cobalt and copper are used for almost all of our blue colors.
