# Compare Website Color Systems Inside Claude Code

The fastest way to compare website color systems in Claude Code is to evaluate each one by role, contrast, repetition, and use in real components, not by collecting isolated hex values. Start with the same checklist for every reference, then choose the system that supports your product's tone and interaction needs.

## Use a four-part comparison

For each website, record four things:

1. **Color roles:** Identify the page background, elevated surfaces, primary text, muted text, borders, brand accent, success state, warning state, and danger state.
2. **Contrast:** Check whether text remains easy to read on its actual background. Test primary text, secondary text, buttons, links, placeholders, and focus or selected states separately.
3. **Frequency:** Note which colors dominate the page and which appear only as accents. A dark green used for one button is a different system from a dark green used across navigation, links, icons, and cards.
4. **Component use:** Compare the same objects across references: navigation, hero, buttons, cards, code blocks, forms, alerts, and footer sections.

This gives you a useful comparison even when the sites have different layouts or content. It also prevents the common mistake of treating the most noticeable color as the whole design system.

Open the examples below and compare the first screen before borrowing a pattern. The cards include Notion Developer Platform, Claude Code, and Exa MCP Server. The observed color set is concentrated around greens, dark neutrals, and muted green-gray tones, including `#496c10`, `#15502e`, `#233f2a`, `#2a966f`, and `#799c92`. Treat these as observed reference colors, not as a ready-made palette for your product.

## Build a side-by-side scorecard

Use a table like this in your notes:

| Question | Reference A | Reference B | Reference C |
|---|---|---|---|
| Main background feels | warm, cool, or neutral | warm, cool, or neutral | warm, cool, or neutral |
| Primary text strength | high, medium, or soft | high, medium, or soft | high, medium, or soft |
| Accent visibility | quiet, balanced, or loud | quiet, balanced, or loud | quiet, balanced, or loud |
| Surface separation | borders, shadows, or color steps | borders, shadows, or color steps | borders, shadows, or color steps |
| Dark-mode behavior | stable, inverted, or mixed | stable, inverted, or mixed | stable, inverted, or mixed |
| Best use case | product UI, editorial, or marketing | product UI, editorial, or marketing | product UI, editorial, or marketing |

Then give each system a 1-to-5 score for readability, hierarchy, brand character, state clarity, and ease of reuse. The score is not a scientific measurement. It is a decision aid that makes tradeoffs visible to a team.

## Separate brand color from interface color

A strong brand color does not need to fill every surface. Decide where it belongs before copying it:

- Use the darkest tone for text, navigation, or high-priority actions only if contrast supports it.
- Use mid tones for buttons, links, illustrations, and selected states.
- Use pale tones for backgrounds, badges, hover states, or grouped content.
- Keep status colors distinct from the brand accent so success, warning, and danger are immediately recognizable.
- Reserve near-black or near-white tones for structure and readability rather than decoration.

If two references use similar greens, compare their surrounding neutrals and spacing before calling them similar. The same accent can feel calm, technical, organic, or playful depending on the background, type, borders, and amount of empty space around it.

## Turn the comparison into a decision

Choose the system that best matches your most important job. For a developer product, prioritize clear code blocks, readable documentation, visible action states, and a restrained accent. For a consumer product, weigh warmth and recognition more heavily. For a marketing page, examine how the palette handles large areas, images, gradients, and calls to action.

Your final brief can be as simple as: “Use a deep green accent for primary actions, a darker green-black for headings, muted green-gray for supporting text and borders, and pale green only for grouped surfaces. Keep status colors separate and verify text contrast for every state.” That is more actionable than a list of twelve hex codes.

## Use this in your AI agent

> Compare the saved website references for their color systems. For each one, list color roles, dominant and accent colors, text and surface contrast, component usage, and dark-mode behavior. Build a side-by-side scorecard, then recommend one system for a developer product. Keep observed colors separate from proposed colors, and finish with a compact palette brief for backgrounds, text, borders, actions, and status states.

Use the same component checklist for every tool: navigation, hero, primary button, secondary button, code block, card, form field, alert, link, and footer. For each component, record the background, text color, border treatment, accent use, hover state, selected state, and any status colors.

Then compare the balance rather than only the palette. Ask whether the accent is reserved for actions or spread across the page, whether code areas use a separate surface, whether muted text remains readable, and whether borders create enough separation without making the interface noisy.

The captured examples below are useful starting points because they include Claude Code alongside Notion Developer Platform and Exa MCP Server. Compare their overall hierarchy first, then inspect the green and green-gray tones as supporting evidence. A practical recommendation might favor the reference with the clearest action states and code readability, even if another has a more memorable accent color.

Paste this prompt:

> Review these website references as color-system examples. Create a table with one row per reference and columns for background, elevated surface, primary text, muted text, border, accent, success, warning, danger, code surface, and button treatment. For each color, include its observed hex value only when available and describe its role in plain language. Note which colors dominate the page and which are reserved for actions or states. Compare contrast and component consistency across navigation, hero, cards, forms, code blocks, and footer. Recommend one direction for my product, explain the tradeoffs, and produce a proposed palette clearly labeled as a proposal rather than an observed fact.

Before accepting the recommendation, check the proposed text colors on their actual backgrounds and verify that status colors remain distinct from the brand accent.
