Generation prompt
This is the submitted prompt. It can guide a similar image; it does not reproduce identical pixels or establish native dimensions.
Use case: stylized-concept. Asset type: a downloadable abstract background for screens, websites and presentations. Create exactly one finished image, widescreen 16:9, requesting native 3840×2160 pixels when available. An overhead abstract ink-on-paper composition with two broad branching channels of diluted indigo pigment entering from the upper right and opening toward the lower center. Pale cool paper occupies the left third. Use natural soft capillary feathering only at the large pigment edges, translucent pools and gently uneven mineral granulation. Keep branching sparse and large-scale, with a clear flow through the central portrait crop. No map, literal river, scenery, cellular patterns, ribbon surfaces or tiny clutter. Palette: #e7e8e5, #758da5, #28455f. Edge-to-edge composition. Preserve useful centered 16:9, 16:10, MacBook, phone and ultrawide crops. No text, lettering, logos, watermark, border, people, tiny clutter, banding, compression artifacts or unwanted recognizable objects.
