Create a ramp (RGB) texture and connect it to the UV Coords of the Image shader. Connect the U Coord of the ramp to the uvcoordsY of the Image shader. Connect the V Coord of the ramp to the uvcoordsX of the Image shader.
Change the ramp type to Four Corner Ramp.
Create four different colors for the ramp: red, yellow, green and blue.

You can change how the image is remapped by adjusting the HSV values of the ramp.

Connect a file or Noise texture to the Color Offset of the Ramp. This will drive the distortion effect.

You could also add a Range or Remap shader in between the file texture and the ramp to further control the effect.
