Demandez à GPT-6 d’analyser la planche et de définir les couleurs, puis confiez la retouche à un outil d’image. Vérifiez les traits et les personnages.

Reddit creators have shared convincing manga-coloring examples with GPT-6, but a polished screenshot does not reveal which image tool actually rendered the pixels. This guide separates visual analysis from image editing and shows you how to verify whether a result preserves your artwork.

Note importante sur les capacités du modèle GPT-6 is not synonymous with an image rendering engine. In ChatGPT, a separate image tool may perform the actual color edit. Do not assume any particular image model is available in LlamaGen.

Check your manga coloring before and after

Choose two images from your device to compare linework, panel borders and character color drift. Images remain in your browser; this page does not upload them. No model is run and no quality score is inferred.

Select both files to activate the visual comparison. Nothing is transmitted.

Tip: compare the same crop at full resolution. This manual overlay is not a pixel-accurate benchmark, alignment algorithm or model performance measurement.

Worked example · editable production brief

Color-lock worksheet for an original manga panel

This is an editorial palette specification to copy into an image editor—not a GPT-6-rendered result. A consistent palette lets you detect redrawn or incorrectly recolored clothing.

Cream jacket · #F4E7CF

Green scarf · #2C826C

Skin shadow · #CB9C78

Guide étape par étape

Follow the sequence using an original or authorized project. The workshop above is an editorial plan, not output falsely attributed to a model.

  1. Step 1

    Start with authorized black-and-white line art

    Use a panel you created or have permission to color. Export a lossless original at its native resolution; keep a separate untouched backup and note its dimensions.

  2. Step 2

    Create a reference color sheet

    For every recurring character list hair, eye, outfit, skin and prop colors. Attach your own colored character sheet when available; do not rely on the model guessing canon colors.

  3. Step 3

    Instruct the assistant to preserve structure

    Tell GPT-6 to analyze the picture and produce a locked palette and explicit regions to color. Specify that gutters, speech bubbles, ink contours and panel layout must remain untouched.

  4. Step 4

    Perform the color edit and compare

    Apply the prompt in an image-edit tool that actually supports image output. Overlay the original and edited versions to look for redrawn fingers, changed line weight, altered text and lost halftones.

  5. Step 5

    Finish for your intended output

    For print, review color mode and export size separately. For a webcomic, inspect small-screen readability and keep each revised panel consistent with the chapter palette.

Prompts à copier

Replace placeholder details with your own original story and reference assets. Paste into a compatible model or workflow; available tools and results differ.

1. Conservative manga color edit

Colorize this original black-and-white manga panel. Preserve every line, panel border, facial expression, object position, screentone, speech balloon and word exactly. Character A: navy hair, amber eyes, cream jacket. Character B: auburn hair, green scarf. Use flat cel shading with subtle shadows. Do not redraw, crop, add lettering, or change the composition.

2. When the image tool keeps redrawing

Compare the proposed edit against the input. Identify every changed contour, face detail, text glyph or panel border. Return a correction list ordered by severity, then create a stricter edit prompt limited to color regions only.

Failure → Cause → Fix

Résoudre les problèmes de création de BD

Specific failure patterns matter more than a generic 'try again'. These fixes target the output you can inspect.

1. An outfit becomes a dark silhouette

Cause probable Global shading was applied without locking fabric color.

Que faire Specify exact clothing colors separately from lighting; reject panels where the base fill changes.

2. Linework or speech text is rewritten

Cause probable The image tool regenerated content instead of making a constrained edit.

Que faire Compare full-resolution input and output; separate color pass from manual lettering.

3. Colors look good in one frame but not the next

Cause probable No shared character reference or canonical color sheet.

Que faire Reuse the same sheet, assign stable IDs and inspect adjacent panels side by side.

Questions fréquentes

Can GPT-6 itself color manga?

GPT-6 can analyze images and coordinate supported image-generation tools. The image tool used by your product or workflow determines the actual pixel output.

Can I color copyrighted manga?

Use artwork you own or have permission to edit and distribute. A third-party Reddit example does not grant reuse rights.

How do I stop the tool changing the drawing?

Ask for color-only changes, supply reference palettes and compare against the original; some image editors still regenerate details, so manual correction may be necessary.
