Phil, in Four Inks

This is my friend Phil. I made his portrait the way a printing press makes color: four sheets of squares, one each for cyan, magenta, yellow and black, each tilted to its own angle (105°, 90°, 75° and 45°) so the grids don’t fight each other. Stack them and a face appears. Pull them apart and each sheet on its own is barely a face at all.

Drag to turn the stack, and use the slider to spread the sheets apart. Switch from ink on paper to light in the dark and watch the same four sheets build Phil by taking light away, then by adding it. In the flat view, double-click (or double-tap) to face him head-on: the sheets line up perfectly no matter how far apart they are, the way they do on a press.

Phil comes in three parts. This is the first; Phil, Out of Register and Phil, Hand-Colored are the other two.

What I’d like to hear: does ink versus light make subtractive color click for you?
