If I am shading in my usual cel shading style (yay) but have been given an image/composition with no interesting lighting (BOO) and the depicted characters are slamming into both #FFFFFF white & near-blacks too dark for me to see, with Satan as my witness, the solution is my standard multiply-or-whatever dark layer for the shadows... and a Level Correction layer on the highlights, proportionally dragging all the darks a little bit towards #FFFFFF.

This feels unethical (I'm not even applying color to the light?! Please, my composition!!) but it works and it doesn't involve me manually adjusting the lightest/darkest character colors, which is otherwise a maze I can lose 45 minutes in, so....
