Experimenting with colour filters

For my final piece i want to have clipping mask letters with images of croydon

and to add extra colour to the design i wanted to experiment with colour filters

so i have these images of different colours and an example of the clipping mask.

Original

 Red

 Green

 Magenta

 Blue

 Different colour levels

 Clipping mask test

I like the designs that consist of single colour filters rather than a multiple colour image.
