So you found the lighting gels then!

I took a little inspiration from a setup I'd seen Jake Hicks create at a workshop, and tried it myself. In all honesty I went about creating the setup the wrong way round... I tried to create the shadow tones, before creating the shadows. Had to rewind my lighting setup and start creating the main light to get the shadows that I can then fill with colour.
