Image Generation prompt
Consistent Flat Vector Illustration Set
Generate a set of matching flat illustrations for a website or app, with locked style rules so every image looks like part of one family.
The prompt
Create a consistent set of flat vector illustrations for {{use}}. Scenes: {{scenes}}.
Style rules (apply identically to every image):
- Flat vector style, no gradients except one subtle shadow tone per colour, no textures.
- Palette strictly limited to: {{palette}}. Use the lightest colour as the background.
- Characters: simplified geometric people with rounded shapes, no facial features except a small nose line, varied skin tones and body types, proportions 1:6 head-to-body.
- Line: no outlines; shapes defined by colour blocks only.
- Composition: single focal scene centred, generous empty space around it, objects grounded on a soft ellipse shadow.
- Perspective: front-facing, slightly elevated, no dramatic angles.
- Detail level: medium — enough props to tell the story, nothing decorative that does not serve it.
For each scene, output a separate prompt that starts with the scene description and ends with the full style block above, so it can be run independently. Aspect ratio 4:3.
Negative prompt for all: 3D, photorealistic, gradients, outlines, text, letters, logos, watermark, busy background, extra limbs, distorted hands. Variables
| Variable | What to put | Example |
|---|---|---|
{{scenes}} | List of scenes to illustrate | 1. Person reading invoices; 2. Team high-fiving; 3. Phone showing a payment notification |
{{palette}} | Four to six hex colours | #1E3A5F, #3DA5D9, #F4D35E, #EE6C4D, #F7F7F2 |
{{use}} | Where the illustrations go | Website feature sections and onboarding screens |
Tips
- Run all prompts with the same seed or style reference image where the tool allows it; that does more for consistency than wording.
- Vectorise the best results (e.g. in a tracing tool) so you can recolour and scale them cleanly.
