- Convert your source image to greyscale. (Either by desaturating it or converting the image mode to grey scale and then back to CMYK/RGB.)
- Add a layer above your image.
- Fill the new layer with a gradient of the colour and angle that you desire. (The example image is a diagonal rainbow.)
- Set the gradient layer to MULTIPLY in the layers pallette.
