Description:

This filter simulates color "crosstalk" exhibited by the 3-strip Technicolor film process (it effectively "pushes" all hues towards the closest of the primary colors: red, green, or blue). The amount of crosstalk is fixed at 50% --if less crosstalk is desired then the filter should be applied to a duplicate of the original layer and the opacity of the result lowered (blending it with the original layer). If more crosstalk is desired, apply the filter twice (again working with a duplicate for finer control).
