"Choice of : Black, Brown, Blue, Green, Red, Orange, White, Yellow\r\nOur pigments are highly concentrated and typically require very little pigment to achieve the desired color. Note : this is not an exact science and your mixed color may vary from batch to batch. They are packaged in a squeeze bottle container for ease of use. The manufacturer of our casting resins suggests that the pigment be added to the B side of the resin."
