Ten motifs, four colours and four numbers is the whole of this generator, and the combinations run far past what you would work through by hand. The motifs are geometric shapes, dots, stripes, waves, circles, triangles, hexagons, chevrons, diamonds and a floral form, each drawn onto a canvas you can export as an image.
The four numbers are where the character comes from. Scale sets how large each element is drawn, spacing sets how far apart they sit, rotation turns the whole field, and opacity decides how far the motif recedes toward the background. Two patterns built from the same motif and colours can look entirely unrelated once those are set differently.
Colour is either yours or picked from eight prepared palettes running from Ocean and Forest through Vintage and Earthy. A pattern takes a foreground colour, a secondary colour and a background, and the palettes are there because three colours chosen at random rarely sit together as well as three chosen to.
PNG and JPG. PNG is the better default because it compresses without introducing artefacts, which matters for the hard edges in geometric motifs. JPG produces smaller files and is reasonable for softer patterns, though it can leave faint halos around high-contrast shapes.
Test it before relying on it. The tool exports a finished image rather than a guaranteed repeat unit, and whether the edges meet cleanly depends on the motif, the scale and the spacing you chose. Place two copies side by side in your design tool and look at the seam; if it shows, adjust the spacing and export again.
It is a raster image at the canvas size, which is generous on screen and modest for a full cover. Use it at or below its exported size, or as a repeated element rather than one stretched image, since enlarging a raster beyond its native resolution softens every edge in it.
