Most AI-generated visuals look cool… but not usable for a real website. The fix is giving ChatGPT a brand-locked briefing that enforces color palettes, spacing, density, and export specs.
When you force ChatGPT to follow rules—minimalism, whitespace, neutral palettes, fixed aspect ratios—clean, brand-ready assets show up every single time.
1. Start With a Brand-Locked Prompt Template
ChatGPT listens closely when you give it clear rules. This template prevents 90% of design problems:
Brand-Ready Image Prompt Framework
Create a clean, modern website hero image. Style: - neutral beige + charcoal palette - soft shadows - simple geometric shapes - clean spacing, no clutter - flat or editorial style Content: - abstract shapes or minimal UI elements - no text unless asked - no heavy gradients or busy details Format: - 1920×1080 - crisp edges - subtle grain <5% Purpose: - must look like a website-ready hero background - easy to overlay typography
Save this. Reuse it. This becomes your baseline for all future images.
2. Add Your Brand’s Look + Rules
If you want consistent visuals, define your brand identity in the prompt. Here’s a Lopez Productions example:
Lopez Productions Branding Rules
Color Palette: - Beige: #EDE6DA - Charcoal: #1E1E1E - Soft Black: #0F0F0F - Warm Neutral Accent: #C8B9A1 Composition: - minimal linework - soft lighting - clean, airy layout - low complexity (< 20% density) - subtle grain texture Avoid: - neon colors - over-saturated elements - complex patterns - photographic realism
Once ChatGPT internalizes your branding, your images stop looking random.
3. Match the Image to the Section You’re Designing
Different website sections need different visual density. Tell ChatGPT the exact use case so it knows how much detail to include.
- Hero Backgrounds: abstract, breathable, 1920×1080, light complexity
- Section Illustrations: simple shapes, small UI windows, subtle line art
- Blog OG Cards: centered composition, slightly denser, 1200×630
- Workflow Graphics: clean device outlines, UI mockups, minimal shadows
Always tell ChatGPT the section. The quality jump is huge.
4. Use Smart Add-On Commands (These Fix Everything)
Try these phrases when tweaking images—they turn a good output into a great one:
- “Reduce visual noise.”
- “Increase whitespace.”
- “Make composition more symmetrical.”
- “Match spacing to Linear.app / Apple.com.”
- “Generate 3 variations with different density levels.”
These micro-commands take a solid image and refine it into premium quality.
5. Export in Proper Web Formats
After generating your image, export intentionally:
- File Formats: PNG for hero sections, JPG for large backgrounds, WebP for fastest performance.
- Target Sizes: Hero < 350 KB, Section art 80–150 KB, OG cards < 200 KB.
- DPI: 72 DPI for web clarity.
- Compression Tools: TinyPNG, Squoosh, Compressor.io.
6. Copy-Paste Prompt Examples
A. Clean Hero Image
Create a clean website hero background in beige and charcoal. Minimal abstract shapes, soft shadows, balanced spacing, subtle texture. No text. Format 1920×1080. Editorial, calm, premium.
B. Blog OG-Card
1200×630 OG-card image in beige and charcoal. Minimal geometric tech elements floating in soft abstract space. Slight shading, no text, subtle grain, centered composition.
C. Illustration
Minimal line-art illustration in beige and charcoal showing abstract AI workflow windows. Clean, simple, flat design. 800×600.
Pro Tip: Iterate Like a Creative Director
Most people stop after one image. The secret? Iterate—regenerate, lighten, simplify, adjust colors, ask for density shifts. Treat ChatGPT like a designer you’re giving feedback to, and your results jump to premium quality.
