Why this beats everything else

Not a palette generator.
A colour intelligence system.

📜
Archive Provenance
Every colour matched to a named historical source. Not "deep blue" — a documented pigment, period, and cultural context from thousands of archive entries.
Others: generic colour names
✓ Documented history for every hex
⊕
True Opposites
Complementary colours matched to archive entries — so your opposite isn't just 180° on a wheel, it's a real colour with documented cultural weight.
Others: basic colour wheel
✓ Archive-matched harmonies
🌐
Cultural Risk
Before a colour goes to market, know its history. Imperial prohibitions, indigenous pigment sovereignty, regional associations. The archive knows what no other tool tracks.
Others: no cultural context
✓ Cross-cultural risk assessment
👁
CVD Simulation
Brettel-Viénot-Mollon model for all three types of colour vision deficiency. See your palette as 300 million people actually see it.
Others: pass/fail labels only
✓ Full CVD visual simulation
☀
LRV & Light Behaviour
Light Reflectance Value for every colour — critical for interior and architectural use. How your palette performs across daylight, atrium, and incandescent illuminants.
Others: no light analysis
✓ LRV + three-illuminant behaviour
⬇
Export Anywhere
CSS variables with archive names as comments. Tailwind config. One click. Your palette ships with cultural context baked into the code.
Others: hex codes only
✓ CSS, Tailwind, with provenance
Common questions
Is this free?▼
The palette architect tool is completely free. No account, no card, no limit. For direct API access — to use Colour Memory inside Claude, or your own products — plans start at £12/month.
How does this compare to Coolors?▼
Coolors generates palettes. Colour Memory diagnoses them against thousands of historically documented colours and tells you why they work or don't — with cultural context, LRV, CVD simulation, and contrast analysis. Coolors gives you hex codes. We give you history.
What is archive provenance and why does it matter?▼
Every colour in the archive is matched to a documented historical source. That context makes your design choices defensible and meaningful — especially important for brand work and international launches.
Can I use this for client work?▼
Yes. The free tool is unlicensed for any use. API access includes commercial use rights from Studio tier upward.
How does cultural risk assessment work?▼
The archive tracks documented cultural restrictions, prohibitions, and sensitivities for colours across many cultural contexts. The risk score flags colours that carry documented negative associations in specific markets — essential before any international brand launch.
