Thermal palette

Start with the right photo.

Choose a source with distinct foreground and background regions so the false-color palette has a readable structure.

What to expect

Apply a false-color thermal palette. This is a visual effect, not a temperature measurement.

Keep an eye on

Recognizable identity, silhouette and important visible details. Compare the output to the original before using it.

Make it yours, step by step.

1. Adjust the recipe to describe your subject and preferred background.
2. Copy the complete recipe, then open ChatGPT.
3. Upload your photo in ChatGPT and paste the recipe. The short code alone is not an official command.
4. Inspect identity, text and proportions. Ask for a targeted correction if needed.

Choose the change deliberately.

Thermal colors are a graphic mapping, not a measurement. Decide which areas should visually separate before applying a palette; uniform rainbow noise makes it difficult to recognize the original face or object.

Review and refine the result

Check silhouette, eye placement and major boundaries after recoloring. If the palette overwhelms the subject, reduce the number of color bands. Do not add numeric temperature legends unless clearly identified as fictional graphic copy.

Where this effect helps — and its limits.

Useful for thermal-inspired graphics. Colors do not measure heat and must not be presented as temperature evidence.
