Procedural backgrounds and mixed shapes

Generate fresh flowing artwork, organic shapes and mixed themes, then combine backgrounds in independent layers.

How do I generate another background?

Press Generate a new background in the top bar, after Redo. It replaces the selected background artwork, not the text or photos above it.

  1. Save the current design if you want an independent snapshot.
  2. Open Appearance and select Base or an overlay in Background layer.
  3. Press Generate a new background in its fixed top-bar position after Redo.
  4. Use Undo if you prefer the previous composition.

Expected result: The selected background has fresh stored geometry and a new identity; foreground content stays in place.

Each generation starts with a cryptographically generated 128-bit seed. Flow backgrounds use a seeded noise field to form paths. Other families vary shape geometry, placement, scale, color and opacity. Color harmonies are generated rather than chosen from a fixed palette list.

The seed provides reproducibility. The artwork itself is also stored, so reopening does not depend on rerunning the current generator.

Kruti generates compositions rather than selecting a finished template. The possibility space is enormous, but a random seed is not mathematical proof of worldwide visual uniqueness. A circle remains a circle; the generated arrangement and appearance provide the variation.

Shape families and the mixed theme

Choose a concrete Style to stay with one family, mixed to combine shapes, or random to pick another family on generation.

  1. Open Background and select the Style tab.
  2. Choose a family or mixed from the Style menu.
  3. Generate again for another seeded composition, optionally keeping the current colors.
  4. Adjust Density, Scale and Flow, then compare the result at the intended post size.

Expected result: Random generation cycles through all available families before repeating during the workspace session. The document stores the resolved style, so reopening preserves the same artwork.

The twenty concrete styles include flow, circles, ellipses, squares, outlines, tiles, waves, confetti, rings, polygons, stars, blobs, petals and spirals. Contours, guilloche and isometric add mathematical line and lattice patterns. Solid and gradient remain available for quieter designs, alongside mixed.

Choose mixed for a composition combining procedural shape families and flowing ribbons. Choose random when the next generation should pick another concrete style rather than staying with one family. The chosen result is stored with its actual style and geometry, so reopening does not reroll it.

Mix themes with independent background layers

Add a background layer, choose its style, and lower its opacity to combine a pattern with the base.

  1. Open Appearance and press Add background layer.
  2. Select the new overlay in Background layer and choose its Style.
  3. Open Layer and adjust Opacity, Blend and order.
  4. Leave Base fill off to show earlier layers; use visibility to compare the result.

Expected result: The base remains intact while the selected overlay adds independently editable artwork.

Use Add background layer to combine different themes without replacing the base. Select the layer you want to edit, then choose its style and colors independently. For example, combine a gradient base, low-opacity blobs and a sparse layer of stars.

The Layer tab controls opacity, normal/multiply/screen blending, visibility and order. Pattern layers omit their base fill by default so earlier backgrounds remain visible; enable Base fill when you deliberately want to cover them.

A background can contain a base and up to twenty additional background layers. Keep busy patterns subtle behind text. Saving and reopening preserves the complete stack and its actual generated geometry.

How do I adjust density or randomize settings?

Use Density, Scale and Flow in the pattern controls. Enable Randomize settings in Style only when Generate should change those values too.

  1. Select a patterned background and open its pattern controls.
  2. Lower Density for fewer marks; adjust Scale and Flow where that style exposes them.
  3. Try Density in the example below and compare the stored circles.
  4. Return to Style and check Randomize settings before Generate if you want fresh settings, not only fresh geometry.

Expected result: Numeric changes affect the chosen background. The palette changes only according to its separate color lock.

Density controls how many marks are generated. Scale changes shape size or field frequency. Flow affects turbulence, wave variation or tile spacing, depending on the family. Gradient angle controls the direction of a gradient.

Generate keeps the selected style, density, scale, flow and angle by default, giving you fresh geometry in the same mood. Enable Randomize settings in the Style tab when those controls should also change. The color lock independently keeps the current palette.

These choices apply to the selected background, including overlays. Opening panels, moving around the canvas and exporting never regenerate the scene.

Add texture finishes to generated background shapes

Open Appearance, choose Colors and select a palette swatch. Choose spray, grain, dots, hatch or scribble in Texture for that color.

  1. Select the base or an overlay in Appearance and choose a patterned style.
  2. Open Colors and select the palette swatch used by the shapes you want to finish.
  3. Choose Texture, then adjust Base ink, Density and Size.
  4. Use None for a smooth color, or Undo to restore the previous finish.

Expected result: Shapes using that palette color receive the seeded finish without moving. The finish stays with generated results, saved files and exports.

A finish applies to a palette color, not to an independently selectable procedural shape. Choosing the first palette color can also texture the base fill. Overlay visibility, blending and opacity remain separate layer controls.

Texture controls are available for patterned and solid backgrounds. Gradient backgrounds keep their smooth multi-color gradient. SVG exports keep these background finishes as reusable vector patterns.

A background stays until you change it

Save or download .kruti to keep the generated geometry. Opening panels, zooming and exporting do not regenerate it.

  1. Generate a composition and save it to the library.
  2. Download a .kruti backup from Files.
  3. Reopen that file and compare the artwork before pressing Generate.

Expected result: The stored composition returns without drawing a new random scene.

Pan, zoom, export, local saving, and opening a saved design use the stored paths. Changing canvas dimensions rescales those normalized paths rather than picking a new scene.

Generate creates a new identity and a new composition. Opening a .kruti file restores its stored scene exactly; applying new appearance settings deliberately recomputes it.
