## Overview

The Krea 2 Style Reference node lets you add a reference image to influence the style of a Krea 2 image generation. You can chain multiple style references together (up to 10 total) and feed the combined result into a Krea 2 Image node. Each image you provide is uploaded to ComfyAPI storage and passed as a URL.

## Inputs

| Parameter         | Data Type  | Required | Range                    | Description                                                                    |
| ----------------- | ---------- | -------- | ------------------------ | ------------------------------------------------------------------------------ |
| `image`           | IMAGE      | Yes      | -                        | Reference image whose style influences the generation.                         |
| `strength`        | FLOAT      | Yes      | -2.0 to 2.0 (step: 0.05) | Reference strength; negative values invert the style influence (default: 1.0). |
| `style_reference` | STYLE\_REF | No       | -                        | Optional incoming chain of style references; this node appends one more.       |

**Note on constraints:** You can chain a maximum of 10 style references in total. If you try to add an 11th reference, the node will raise an error.

## Outputs

| Output Name       | Data Type  | Description                                                                                                             |
| ----------------- | ---------- | ----------------------------------------------------------------------------------------------------------------------- |
| `style_reference` | STYLE\_REF | A list of style reference entries, each containing a URL and strength value. Feed this output into a Krea 2 Image node. |
