| Time After Application | Mehendi Colour | Notes / Tips |
| 0–6 hours | Orange stain | The initial stain appears; don’t worry if it’s light. |
| 12 hours | Rust brown | Colour begins to deepen; avoid water contact. |
| 24 hours | Deeper tone | Mehendi is richer; warmth helps oxidation. |
| 48 hours | Final maroon shade | Peak colour: your mehendi is fully developed. |
