Luikki
Luikki reads your inked page, builds every flat zone, and colors them from your own character sheets and the pages you've already finished. Nothing is locked in: every zone stays a layer you can repaint.
Drop in the inked page. Luikki finds the panel borders first, so no color bleeds from one panel into the next.
Balloons, captions and gutters are recognised as regions of their own: they stay white because you want them to, not because they were missed.
Stand-in colors make each region visible: an open line or a leak can't slip past you.
Merge zones and split them however you like. The structure is right before a single real color touches the page.
Luikki matches each zone to the palette you defined for your characters, props and sets.
Named, layered PSD export: one group per panel or per color. Open it in your app of choice and keep working the way you always have.
Luikki is in private testing with a small group of colorists and studios. Tell us how you work and we'll open a seat for you as soon as we can.
