Apply Color Grade from Reference Image
The easiest way to match color grades between your images. Upload a target image and a reference image that has the desired colors and use Nano Banana 2 to extract and apply it onto the target image.
About
This ComfyUI workflow applies the color grade from a reference image to one or more target images, giving you a fast, consistent way to match looks across shots. It starts with LoadImage nodes for both the target and the reference. The core of the pipeline is the GeminiNanoBanana2 node (Nano Banana 2), which analyzes the reference image’s color distribution and computes a global color transform. That transform is then applied to the target image to reproduce the reference’s overall palette, contrast feel, and mood without altering composition or sharpness.

GeminiNanoBanana2 analyzes the reference image’s color characteristics and computes a global color mapping that is applied to the target image. It transfers the look (palette and overall grade) without changing composition, detail, or geometry.
No. The grade transfer is based on color distribution, not spatial layout. However, for best results, choose a reference with similar lighting and exposure to your target to avoid extreme corrections.
Yes. Use BatchImagesNode to pass multiple target images through the pipeline. Each will receive the same reference-based grade, and SaveImage will write out each processed result.
No. The workflow transfers color characteristics only. Texture, grain, or local detail from the reference isn’t copied. If you need grain or film emulation, apply it as a separate step outside this workflow.
