FAQ

Do these tools call an AI service?

No. These P1 preview tools parse and render locally in the browser by default.

Do they replace the real runtime?

No. They are quick preview and debugging surfaces. Your real API, browser, or design system remains the final authority.

Color Palette Preview is part of the DiagramPreview P1 preview toolbox.

It focuses on the review step after AI generation and before publishing, turning text snippets into inspectable structure and visual output.

Use it alongside HTML, CSS, JSON, Base64, API, and configuration preview tools.

Demo: review a product color palette

Palette previews help teams see brand, status, surface, and text colors together instead of judging isolated hex values.

Check adjacent contrast for text and UI labels.
Separate semantic colors from decorative colors.
Preview colors as swatches and real UI roles.

--color-success: #16a34a;
--color-warning: #f59e0b;
--color-ink: #0f172a;

Accessibility checklist: color is not only taste

A good palette must support readability and state recognition. Preview contrast and semantic usage before applying colors across the site.

Do not communicate errors with color alone.
Check text contrast on surface and tinted backgrounds.
Keep status colors distinct for common color-vision deficiencies.

body text on surface: >= 4.5:1
large text: >= 3:1
icon-only status: add label or shape

Review checklist for Color Palette Preview

Use Color Palette Preview when you need to inspect source content visually before it becomes documentation, a pull request note, an incident write-up, or a handoff artifact. Preview hex, rgb, hsl, and CSS variable palettes with adjacent contrast checks.

Before exporting, check that labels are readable, relationships match the source, generated examples do not contain private data, and the preview still makes sense after you edit the input.

Limits and troubleshooting

If the preview fails, reduce the input to the smallest complete example, confirm the format syntax, and then add sections back one at a time. Many rendering failures come from partial files, indentation mistakes, missing diagram headers, or copied snippets that depend on hidden context.

Treat the preview as a review surface rather than a source of truth. Generated diagrams, converted files, dashboards, and rule examples should be checked before they are used in production documentation or operations.

Tool maturity

Stable renderer

Stable tool

This tool has a dedicated renderer or preview surface, useful exports, and a repeatable browser-first workflow.

The maturity label is not a quality score. It tells visitors whether the tool is best for stable export, deeper debugging, quick parsing, or AI-assisted generation.
