![ComfyUI Built-in Krea 2 Style Reference Node](/images/built-in-nodes/api_nodes/krea/krea2-style-reference.jpg)
9+
10+
The Krea 2 Style Reference node adds an image style reference to a Krea 2 generation. Chain multiple Krea 2 Style Reference nodes (max 10) and feed the final `style_reference` output into Krea 2 Image. Each image is uploaded to ComfyAPI storage and passed as URL.
11+
12+
## Parameters
13+
14+
| Parameter | Type | Default | Description |
15+
| --------------- | ------ | ------- | ---------------------------------------------- |
16+
| image | image | — | Reference image whose style influences the generation |
17+
| strength | float | 1.0 | Reference strength (-2.0 to 2.0) |
18+
| style_reference | chain | — | Optional incoming chain of style references |
19+
20+
### Strength
21+
22+
The `strength` parameter controls how strongly the reference image's style influences the output:
23+
24+
- **Positive values (0.0 to 2.0):** Apply the reference style with increasing intensity
25+
- **Negative values (-2.0 to 0.0):** Invert the style influence
26+
- **0.0:** No style influence
27+
28+
## Output
29+
30+
| Output | Type | Description |
31+
| --------------- | ----- | ---------------------------------------- |
32+
| style_reference | chain | Chained style reference for Krea 2 Image |
