For the past several months Carol Simmons has been posting a series of well thought out and detailed articles on her blog in response to the discontinuation of two essential primaries -Cobalt Blue and Zinc Yellow – in Premo by Polyform Products. For those of us that mix our own colors and teach about color using polymer clay….Denim blue and Sunshine yellow are NOT acceptable substitutes.
Carol has annotated Maggie Maggio’s color triangle color chart on her site to help illustrate the loss of Zinc yellow and Cobalt Blue.
Note: For the time being the remaining stock of those two colors is available from Polymer Clay Express.
