Eye Color
Recolor the irises in a portrait. The customer describes the target eye color (e.g. "blue", "emerald green", "amber") — that drives the inpaint guidance. Optional RGB lets you tint the overlay precisely.

Overview
**Eye Color** recolors the irises in a portrait. Describe the target eye color in plain language ("blue", "emerald green", "amber", "deep brown") and the pipeline performs a face-aware inpaint + upscale that preserves natural eye texture, eyelash detail, and surrounding skin. RGB channel values let you tint the colour overlay precisely.
How it works
Provide an image URL, the inner filename in the bundle (`file_input`), the customer-facing target eye colour (`eye_color`), and three RGB channel values. A face-detection step locates the eyes; an inpainting + upscaling pass recolours the irises using `eye_color` to drive the guidance prompt, while preserving anatomical detail.
Common use cases
- Portrait retouching at scale
- Cosmetic-product visualization (lens campaigns)
- Stylized portrait variations

Frequently asked questions
- What is the Eye Color model?
- A first-party Runflow workflow that recolors the irises in a portrait to any RGB value you specify, while preserving natural eye and skin detail.
- How much does Eye Color cost on Runflow?
- Simple fixed pricing: $0.29 per image.
- Does it work on multiple faces?
- It targets the most prominent face in the image. For multi-subject group shots use a face-detection step upstream and run per face.
- Can I use a natural-language description instead of RGB?
- No — color is RGB-only for predictable results. We may add a prompt-based variant later.
- How long does Eye Color take?
- 60–120 seconds typically.
- Can I use the outputs commercially?
- Yes.
Related models
- Multi Angles, Re-render the same subject from a different camera angle. Pick a horizontal view, a vertical angle, and a shot distance: the model rotates the camera around the subject and re-renders the scene from that pose.
- Logo Inpaint, Place a logo onto a target image, with optional mask to constrain placement. When the mask is omitted, the workflow picks a placement automatically.
- Background Replace, Swap the background of any product photo for a new scene defined by a reference image and a short prompt. The model preserves the foreground subject while matching camera angle and lighting to the new background.
- Reference Inpaint, Inpaint a region of a target photo using a reference image as the visual guide. Provide the target, a black-and-white mask of the area to fill, and a reference image. The model paints the masked region with content matching the reference.
