Style Reference (--sref)
Comprehensive Calibration Guide, Syntax & Recommended Values
Transfers the complete aesthetic palette, color grading, brushstrokes, and visual vibe from reference images onto a new prompt subject without copying the reference subject.
How Style Reference (--sref) Operates Internally
The Style Reference parameter (--sref) is one of the most powerful features in Midjourney v6.1. By appending one or more public image URLs, Midjourney extracts abstract stylistic features—such as chromatic grading, painterly strokes, lighting intensity, and film grain—and applies them to whatever new subject you describe. Unlike image prompts which influence composition and subject matter, --sref influences aesthetic texture exclusively.
Recommended Value Calibration Matrix
| Setting / Syntax | Target Scenario | Visual Result & Impact |
|---|---|---|
| --sref <URL> | Standard Style Mimicry | Transfers balanced color palette and textural mood from a single reference image. |
| --sref <URL1> <URL2> --sw 250 | Blended Multi-Style Harmony | Harmonizes two contrasting aesthetic references with gentle, non-destructive style weight. |
| --sref <URL> --sw 800 | Aggressive Aesthetic Override | Forces near-total adherence to the reference medium (e.g. vintage risograph, neon ink). |
| --sref random | Serendipitous Style Discovery | Generates a randomized style seed code from Midjourney's internal aesthetic latent space. |
Common Mistakes & Syntax Errors
- •Using local file paths instead of publicly accessible direct image URLs (ending in .jpg, .png, .webp).
- •Passing references with strong subjects expecting the subject to transfer—use character reference (--cref) for faces and subjects instead.
- •Combining excessively high --sw (e.g. 1000) with complex subjects, which causes subject loss and pure abstract textures.

Style Reference (--sref) Frequently Asked Questions
How does --sref differ from standard image prompts in Midjourney?
Standard image prompts influence composition, geometry, and subject identity. The --sref flag extracts only the aesthetic vibe, color palette, lighting temperature, and medium texture, leaving the new subject completely free.
Can I use multiple style references simultaneously?
Yes. You can supply multiple URLs separated by spaces (e.g. --sref URL1 URL2). Midjourney will blend their visual styles evenly, or you can apply relative weights like URL1::2 URL2::1.
