Try it yourself
How it works
No pipeline to build, no models to configure.
Send image + target color
Pull a photo with visible eyes and specify the desired color — standard name (blue, green, hazel, brown, gray, amber) or custom hex.
AI changes the eye color
Runflow's pipeline detects the irises, applies the color, and preserves natural reflections, pupil detail, and lighting consistency.
Get your result
Receive the image with a natural-looking eye color change — ready for your user, under 2 seconds per image.
Photorealistic iris color change
The API changes iris color while preserving natural light reflections, pupil detail, and the subtle color variations found in real eyes. The result is indistinguishable from a natural eye color in the original photo — no painted-on look, no flat color fills.
Any target color — standard or custom
Blue, green, hazel, brown, gray, amber, or any custom hex color. The API adapts the chosen color to the existing lighting conditions so it looks natural in context — bright studio shots, moody editorial, or low-light portraits.
Works with glasses, gaze, and both eyes
Both eyes are changed consistently — same color, same intensity, same natural variation. Works with glasses, sunglasses, any gaze direction, and partial occlusion. No manual masking or per-eye configuration required.
Plug-and-play feature for your product
Send an image and a target color. Get the result in under 2 seconds. No masks, no selection tools, no manual input from your users. Ship eye color customization as a feature in days, not months.
