Visual Intelligence Index™
Over a million palettes. One standard to measure them.
Huevex holds more than one million color systems, palettes, gradients and swatches, built on brand color data from up to 75,000 brands in each of 20 industries. Every one is scored on the six things that decide whether a color system holds up in a real UI.

measures in every score
Up to six measures. One score out of 10.
- Anchor Strength
Does one color clearly lead and give the brand an identity people recognize?
- Role Separation
Does each color have its own job (primary, secondary, accent) without competing?
- Value Range
Is there enough light-to-dark contrast to build hierarchy?
- Chroma Rhythm
Are vivid and muted colors placed with purpose, not by accident?
- Use Range
Do the colors hold up across backgrounds, type, accents and real brand applications?
- Brief Fit
Does the palette suit the audience, personality and purpose it was made for?

Questions people ask before they sign up
- Why should I trust the scores?
- A score is arithmetic on your palette, not an opinion. Each one is built from up to six measures: anchor strength, role separation, value range, chroma rhythm, use range and brief fit. The breakdown is shown next to the number, so you can disagree with one measure instead of with a black box.
- Does Foundry give me real tokens?
- Yes. Foundry exports CSS variables, SCSS, a Tailwind config and JSON, alongside ASE, PDF and the HEX list, so what you copy out is what your code consumes.
- What do I get free?
- A free Explorer account gets 2 generation credits a day, unlimited browsing of the 1,000,000+ palette library, palette scoring and the HEX export. No credit card, no time limit.
- Can I get my palettes out?
- Every palette and color system copies as HEX values. Foundry adds ASE, PDF, CSS, SCSS, Tailwind and JSON, and a full system exports as one set rather than color by color.
