This is small and simple Python Effector that delays clone’s color. Effector takes clone’s incoming color value and mixes it with clone’s previous color by the amount of delay variable in percentages. Therefore you have to use quite high delay value to get visible effect.
N.B. I recomend using Delay and Decay Field Modifier Layers in newer Cinema 4D versions instead of this effector.
