How to Try Cherry Red Hair on Your Saved AI Character

Curious about cherry red hair, but want to explore the look before changing your style? A saved character gives you a personal starting point for trying a new color. Instead of describing the person from scratch for every image, you can reference a character you have already created and focus your prompt on the hair.

This tutorial shows how to change hair color with AI using a saved Idoli character. The aim is a rich cherry red look with depth in the shadows and soft highlights, while asking the model to retain the existing hairstyle. The results are styling inspiration, rather than an exact prediction of how dye will look on your real hair.

1. Define the Cherry Red Look You Want

For this look, aim for a deep cherry red base rather than a bright neon red. The darker areas should still show strands and texture, while the sections catching the light should reveal softer reddish highlights. The color should follow the hair instead of appearing as a solid painted shape.

Keep the existing hairstyle as the starting point. If the character has bangs, waves, or a particular hair length, include those details among the features you want to preserve. A chest-up portrait with soft neutral lighting makes the color easier to inspect without a strong colored light changing its appearance.

2. Create and Save Your Character

If you already have a saved character, skip to the next step.

To create one from a photo, open character creation in Idoli and upload a photo you have permission to use. Enter:

Generate a character based on the reference image.

Check the generated appearance, use Fine-tune for any details you want to adjust, and save the character when you are satisfied. Character creation does not currently have conversation memory, so use Fine-tune for these adjustments.

You can also design an original appearance in image generation first, then use the chosen image as the reference for character creation. Complete the character creation and saving steps before moving on. An ordinary generated image is not automatically a saved character.

A character created from a photo is a generated interpretation of that appearance. It does not need to be an exact copy of the person pictured to serve as a starting point for exploring hairstyles and colors.

3. Reference Your Character and Use the Template

Open image generation and select the saved character you want to use. Then open the cherry red AI hair color change template for the default prompt and generation entry point.

Make sure the character selected in the interface matches the character reference used in your prompt. Typing a name alone does not replace selecting and referencing the saved character. The example below uses one character reference; use your selected character’s reference in its place.

Change @coser’s hair color to a rich cherry red, with deeper red tones in the shadows and soft reddish highlights where the light catches individual strands. Preserve the character’s recognizable facial features, existing hairstyle, bangs, hair length, and hair texture. Keep the eyebrows their original color. Keep the skin tone, eyes, clothing, and background colors unchanged. Avoid neon red, flat color blocks, and red color bleeding onto the face. Use a chest-up portrait with the shoulders turned slightly and the face looking toward the camera. Keep the full hairstyle within the frame. Soft neutral lighting, a simple background, realistic hair detail, and natural color transitions from roots to ends. Vertical 3:4 composition.

Choose the 3:4 portrait setting if it is available for your selected model. The preservation instructions describe the intended result; they do not guarantee that every facial, clothing, or background detail will remain identical.

4. Check More Than the Color

Compare the result with your saved character. A convincing cherry red hair image needs both a useful color preview and a recognizable starting appearance.

• Check whether the hairstyle, bangs, parting, and length still resemble the original character.
• Look at the eyebrows, skin, and eyes for unwanted color changes.
• Inspect the crown, sides, and ends for visible strands and natural changes in brightness.
• Check the hairline and cheeks for red color spilling beyond the hair.
• Look for clipped hair at the frame edges, flat red patches, or highlights that appear neon.

If the face or hairstyle has changed substantially, address that before making smaller color refinements. Comparing different colors becomes less useful when the underlying appearance also changes.

5. Refine the Color with Short Follow-Up Prompts

Idoli’s image generation conversations have context memory. After the first result, you can continue in the same conversation with a short adjustment instead of repeating the entire prompt. Change one aspect at a time so it is easier to see what each instruction does.

If the red feels too vivid:

Reduce the red saturation slightly while keeping the hairstyle unchanged.

If the shadows need more depth:

Deepen the shadow tones while keeping the cherry red highlights soft.

If the hair looks too flat:

Add subtle tonal variation between individual strands while keeping the overall cherry red shade.

To target a particular result, choose Edit only this image. This adds the selected image to the conversation as a reference, so your next instruction can focus on that image. If a long conversation starts producing conflicting changes or drifting away from your intended look, start a new conversation, reference the saved character again, and provide the current color requirements.

Explore Another Color

For a chocolate brown or copper red variation, update the base color together with the shadow and highlight descriptions. When starting from the full template, also replace the red-specific color-control instructions so they match the new shade.

For chocolate brown, you can use this color description:

Use a rich chocolate brown hair color, with deeper brown shadows and soft warm brown highlights. Keep the existing hairstyle and hair length.

For copper red:

Use a warm copper red hair color, with deeper auburn shadows and soft copper highlights. Keep the existing hairstyle and hair length.

Soft beige brown is another option if you prefer a gentler brown with a muted beige tone. Keep the pose and lighting instructions similar when comparing colors, and check whether differences in the generated hairstyle are affecting your preference.

Once you have a shade you want to explore, return to the cherry red hair template for the full portrait structure and adapt its color instructions.
