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.

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
