The best way to get a color system from a live website is to identify repeated color roles, not merely collect the most visible hex values. Separate backgrounds, text, borders, actions, status colors, gradients, and decorative colors, then verify where each value appears before naming it as a reusable token.
Start with color roles
Review a homepage, a content page, and an interaction state such as a form, menu, dialog, or selected control. For every color, record the value, role, page, component, state, and background beside it. Useful roles include:
- Page and alternate backgrounds
- Surface and raised-panel colors
- Primary and secondary text
- Borders and dividers
- Links and buttons
- Success, warning, error, and selected states
- Focus indicators
- Gradients, illustrations, and photographic colors
A color sampled from a hero illustration should not become a brand token automatically. First check whether it repeats in interface components and remains meaningful across page states.
Use a table like this:
| Role | Sample | Where it appears | State | Confidence |
|---|---|---|---|---|
| Page background | hex value | outer canvas | default | high |
| Main text | hex value | headings and body | default | high |
| Muted text | hex value | metadata and hints | default | medium |
| Accent | hex value | links and actions | default | medium |
| Border | hex value | cards and separators | default | medium |
The sample values should come from the site you are reviewing. A palette list is not a complete color system until each value has a role and repeated evidence.

Read the captured examples carefully
The captured Pangram example includes a muted green direction with values such as #496c10, #15502e, #14532d, #233f2a, and #2c7a4a, plus lighter green and gray-green tones. These are observed colors from that capture. They are not universal recommendations and do not establish Pangram's official token names.
Color relationships matter more than isolated swatches. A dark green may serve as an action background, while another dark green may be text. A pale tone may be a surface or selected state. Similar values can have different roles, and one role can have different default, hover, focus, and disabled values.
Build a usable token set
After checking the roles, organize the values by purpose:
The CSS values above are placeholders for a review workflow. If you are documenting the captured green direction, keep the observed hex values beside their locations and explain which ones repeat. Do not collapse every shade into one primary color. A practical system may need separate values for actions, text, surfaces, borders, focus, and status states.
Check contrast using the actual text size, weight, and background. Test muted text, button labels, links, placeholders, focus outlines, and disabled text separately. A color can look balanced in a palette and still become difficult to read in a real component. Record any accessibility adjustment beside the observed value instead of silently replacing it.
Verify before export
Before reusing the result, ask:
- Does each proposed token appear more than once?
- Is the color tied to an interface role rather than only an image?
- Are default, hover, focus, disabled, and selected states represented?
- Is text readable on every background where it appears?
- Are gradients and transparency recorded separately from solid fills?
- Have brand colors been kept distinct from decorative colors?
Fudge lets you inspect captured color roles, frequency, contrast, gradients, borders, and component styles. That helps compare repeated uses across a page instead of relying on one screenshot sample. Export only after marking which details were directly observed and which names or mappings were inferred for reuse.
Use this in your AI agent
> Review the captured website and extract its observed color system. Group colors by role, including backgrounds, surfaces, text, muted text, borders, actions, links, status states, focus states, gradients, and decorative colors. Report hex values, where each value appears, repetition, contrast concerns, and confidence. Return provisional CSS tokens, but clearly separate observed details from inferred design-system names.
Install Fudge for your AI agent to inspect captured pages and organize repeated colors into a practical reference.
How can I turn sampled website colors into accessible design tokens?
Separate the visual palette from the usable roles. A sampled dark green might be a button background, heading color, or illustration shade, and each use should be checked independently. Assign a role only after testing the color against the background where it will appear.
For each text color, record its intended size and weight, then test it on every relevant surface. Do the same for button labels, links, placeholders, focus outlines, and disabled states. If the observed value does not provide enough contrast, record both the observed color and the safer implementation value.
A useful structure is:
This preserves an honest visual reference while making the implementation safer to use.
What should I export after reviewing a website's color system?
Export a role-based token table alongside the raw observed colors. Include each value's usage locations, state variants, contrast notes, and confidence. For example:
| Token | Value | Role | States | Evidence |
|---|---|---|---|---|
| color-background | hex | page canvas | default | repeated on three pages |
| color-text-muted | hex | secondary copy | default | metadata and hints |
| color-accent | hex | primary action | default, hover | buttons and links |
| color-focus | hex | keyboard focus | focus | form controls |
Add a short list of colors that should not become tokens, such as one-off illustration shades or colors sampled from photographs. Label the file as an observed recreation unless the site's public documentation confirms its source variables or official names.
If you are rebuilding the style, CSS or Tailwind-ready values are practical outputs. When comparing several references, keep each raw palette separate first, then map them into shared roles.
