What Is a Random Design Generator?
This random design generator has five modes, each with its own Generate button: a five-color palette (built on a mono, complementary, triadic, analogous or split-complementary scheme), a linear or radial gradient, a heading and body font pairing from 15 Google Fonts pairs, a grid layout sketch, and a written design prompt. Use it to break creative blocks and explore directions you would not have picked yourself.
Breaking Creative Blocks
Staring at a blank canvas is the designer's equivalent of writer's block. Random generation helps by removing the pressure of choosing. When the tool makes the first choice for you, you only need to judge the result — which is much easier than creating from scratch. Use random designs as starting points, not final outputs. Tweak the ones you like, discard the rest.
How to Use This Tool
- Click Generate — Pick a mode (palette, gradient, font pair, layout or prompt), then click Generate for a new random result in that mode.
- Explore variations — Keep clicking to browse results. Copy the CSS (palette, gradient, font pair) or the prompt text for the ones that spark ideas.
- Lock what you like — In palette mode, lock individual colors you like; the next Generate keeps them and replaces the rest.
- Use as inspiration — Take the generated design as a starting point for your own work — adapt colors, type, and composition to fit your project.
Worked example: how one palette is built
Each palette starts from a random base hue on the 360° colour wheel. Say it lands on 200° (a sky blue). The scheme then sets the hue of each of the five swatches:
| Scheme | Hues of swatches 1 to 5 |
|---|---|
| Mono | 200°, 200°, 200°, 200°, 200° |
| Complementary | 200°, 200°, 20°, 20°, 200° |
| Triadic | 200°, 320°, 80°, 200°, 320° |
| Analogous | 200°, 230°, 260°, 290°, 320° |
| Split-complementary | 200°, 350°, 50°, 200°, 20° |
Saturation is random between 50% and 79% for every swatch, and lightness steps up across the row: swatch 1 sits between 10% and 19%, then 25-34%, 40-49%, 55-64% and 70-79%. That is why every palette runs dark to light and always has a near-black and a pale colour you can use for text and background. Note that this tool's split-complementary mode also includes the direct complement (20°) as its fifth swatch, which a strict split-complementary scheme leaves out.
How often things repeat. Font pairs come from a list of 15, so repeats arrive quickly: the chance of seeing at least one repeat is 19% within 3 clicks, 53% within 5 and 90% within 8. Palettes and gradients draw from continuous ranges, so an exact repeat is very unlikely.
