RGB split effect
Separate each component's RGB(red, green, blue) colors and display them on the screen with an offset:

This effect is also known as chromatic aberration. Each color channel has its own X and Y offset, so you can push the red, green and blue apart in different directions. Larger offsets create a stronger glitch or old-lens look, while small offsets give a subtle color fringe. Set every offset to 0 to disable the effect.
