Color · A CGA primitive

Black and white in.Color out.

Color takes a B&W still and renders it in color. Composition stays exactly where you put it. Edge ControlNet locks every line, shape, and angle you already approved. Only the palette and the light change.

Why this exists

Composition is the hard problem. Color is decoration on top of composition.

Real productions lock composition first. Block in monochrome, work out the shapes, decide what the eye lands on. Once that decision is made, color comes next. A century of cinema works in this order because it is the order that holds up.

Most AI tools collapse the two stages. You write a prompt, the model commits to color and composition at the same time, and a regen changes both. You lose the composition you liked. You start over.

Color separates the two. You bring a composition you already approved. Color rerenders the palette and the light without touching the lines. Same frame. New look. As many times as you want.

How Color works

Four steps from black and white to color.

Color uses edge ControlNet to extract the lines from your B&W still and uses them as a skeleton the new render cannot break. The composition is locked. Only the palette and the light change.

i
Upload

Drag in a B&W still. Storyboard frame, contact sheet, monochrome render. Any image with a composition you already like.

ii
Style

Pick a Style profile if you have one. Color reads its palette and tone signals and feeds them into the prompt. Skip this step if you want a clean default.

iii
Render

Edge ControlNet extracts the lines. Flux Canny Pro repaints the palette and the light. Around fifteen seconds per render. Composition stays.

iv
Compare

B&W reference and color render side by side. Regenerate for a variation. Download when you have the version you want.

What you take home

A color version of the frame you already approved.

Not a different shot. Not a reinterpretation. The same frame, repainted. Drop it back into your storyboard, your edit, your deck.

  • Color renderA full-resolution JPG of your B&W frame, repainted in color with composition preserved by edge ControlNet.
  • Side-by-sideYour B&W reference and the color render shown together, so you can verify the composition stayed locked before you commit.
  • RegenerateVariations of the same frame at no extra step. Try a warmer light, a different tone, a different palette. Composition does not change.
  • DownloadA clean JPG you can drop into Premiere, Photoshop, a deck, a contact sheet, or a brief. Your image, your file.
