The quickest way to analyze a live website color palette is to collect the colors that appear repeatedly, group them by visual purpose, and then test each important combination for readability. A useful result is not just a list of hex values: it is a small palette that tells you which colors belong in backgrounds, text, buttons, borders, links, and accents.

Use a four-part palette method

Start with four groups:

1. Brand colors: the colors that make the site recognizable, such as a main green, blue, orange, or purple.
2. Text colors: the darkest colors used for headings, body copy, labels, and muted text.
3. Surface colors: page backgrounds, cards, navigation bars, input fields, and other large areas.
4. Action and status colors: buttons, links, focus states, success messages, warnings, and errors.

For each group, record the hex value, where it appears, and how often it appears. Keep near-duplicates together at first. A site may use several greens that look similar but serve different jobs. The first pass should preserve those differences rather than flattening everything into one average color.

Open the examples below and compare the first screen before borrowing a pattern. The captured muted-green direction includes colors such as #496c10, #15502e, #14532d, #233f2a, and #799c92. Treat these as observed reference values from the example, not as a universal recommendation for every website.

Turn raw colors into a usable shortlist

A practical palette usually needs fewer colors than the page initially appears to contain. After collecting the values, sort them into a shortlist:

• Primary: the strongest recurring brand color.
• Primary dark: a darker version for text, hover states, or emphasis.
• Primary light: a softer version for tinted surfaces or selected states.
• Ink: the main text color.
• Muted ink: secondary text and metadata.
• Surface: the main background.
• Border: dividers, cards, fields, and subtle outlines.
• Accent or status: a color with a clear action or feedback role.

Do not choose colors only because they look good in a swatch grid. Check them on the actual page. A dark green may work well for a button but feel too heavy as a full-page background. A pale green may work as a panel fill but disappear behind small text.

Check contrast where people need to read

Review the most important pairings first: body text on the main background, button text on button fills, links on page surfaces, text inside cards, and placeholder or disabled text in fields. Compare both normal text and larger headings because size changes how much contrast is needed.

Also inspect non-text signals. Focus rings, error borders, selected tabs, and chart colors should not depend on color alone. Pair a color change with a border, icon, label, underline, or position change when the state matters.

A simple review checklist:

• Can you read body copy without zooming in?
• Can you distinguish links from nearby text?
• Does button text remain clear in every state?
• Can you tell disabled, focused, selected, and error states apart?
• Do the colors still make sense over both light and dark surfaces?
• Are similar colors doing different jobs without confusing users?

Create a handoff that stays tied to the page

For each final color, save the value, role, example location, and a short usage note. For example: "Dark green, primary action, filled buttons and active controls, use light text on top." This is more useful than naming a color "green 700" without explaining where it belongs.

Remember that a palette extracted from a live website describes what is visibly used on that captured page. It does not automatically prove that you have the site's official internal design system, source variables, or complete state coverage. If you need a production-ready system, verify the values against the site's source styles and test pages beyond the initial view.

Use this in your AI agent

> Analyze the captured website's color palette. Return a concise table of observed hex values grouped into brand, text, surface, border, action, and status colors. For each color, include its likely role, where it appears, whether it repeats, and any contrast or readability concern. Keep observed values separate from recommendations, then propose a smaller practical palette for recreating the page.

Start with repetition and responsibility, not just visual similarity. A color is a strong token candidate when it appears in several places or controls a repeated state, such as primary buttons, links, borders, cards, or success messages.

Group close values by job and compare their actual use. If two greens appear in buttons with different states, keep separate tokens even if they look nearly identical. If five gray values all appear as one-off shadows or anti-aliased edges, do not promote all five into the core system.

For each candidate, record four things: the color value, the role, the surfaces it can sit on, and the states where it changes. A useful token name describes the job, such as color-action-primary, color-text-muted, or color-surface-subtle, rather than only describing the hue.

Then test the token across a small matrix: light background, dark background, normal text, large text, button text, focus state, and disabled state. Keep a color as a token only when its role remains clear across the places where it is expected to work. If a value needs frequent exceptions, split the role or treat it as a local component color instead.

Include the observed value, the proposed token name, the visual role, and one or two page examples. A compact table is usually enough:

Add a separate section for states: hover, pressed, focus, selected, success, warning, and error. Note whether each state is a separate observed color or a proposed adjustment.

Also include contrast checks for the combinations users must read or act on. Point out where color alone could be ambiguous, such as selected navigation, validation errors, or focus indicators. Finally, label the boundary of the review: which page and viewport were checked, which states were visible, and which values still need verification in source styles or additional screens.

That distinction keeps the handoff honest. It tells developers what the page visibly uses and what still requires design-system confirmation.
