Overview

RGB Split splits the red, green, and blue channels of a layer, keeping one fixed and shifting the other two channels in opposite directions.

RGB Split is used in a wide number of effects, as a part of 80s or VHS style effects, various glitch effects, and much more. It has four parameters, Strength, Angle, Center, and Mode.

Strength changes the amount of separation between channels. Higher values create a larger separation.

Angle changes the angle of displacement for the two shifting channels. At zero degrees, the displacement is horizontal. Increasing the value of Angle will change the angle of displacement in a clockwise orientation.

Center determines which channel remains centered during the channel split.  Assuming an angle of zero degrees. If Red (R) is selected, blue will be displaced left, and green will be displaced right. If Green (G) is selected, blue will be displaced left, and red will be displaced right. If Blue (B) is selected, green will be displaced left, and red will be displaced right.

Mode determines how the split channels are combined into the final image. Light, Dark, and Mask affect how opaque parts of the layer bleed into transparent parts. Light bleeds lighter, Dark bleeds darker, and Mask has no bleed. Luma provides a less accurate but sometimes more pleasing cross-mixture of the RGB channels.
