The ColorCore process allows us to control the color and density of Tiffen filters, and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations.When Tiffen filters are ground and polished, the ColorCore is unaffected, so color and density remain uniform.
