Build a Color Palette Extractor with Claude Code

Build a Color Palette Extractor web app. People search for "color palette extractor" about 700 times a month, plus related searches like "extract colors from image", "color picker from photo", "image color palette". The goal is a tool that ranks for those searches and makes money.

What it should do:
Build a color palette extractor web app. Create a homepage with image upload showing instant color extraction preview. When users upload an image, display extracted color swatches with hex codes, RGB values, and HSL information. Add palette size options (3, 5, 8, 12 colors) and extraction methods (dominant, vibrant, muted). Include color harmony suggestions and export options (CSS, SCSS, Adobe Swatch). Show color accessibility ratings and usage examples. Use colorful design with dynamic palette previews. Focus on image upload and color extraction first.

How to build it:
1. Read this folder first. If it is empty, set up Next.js (App Router, TypeScript, Tailwind). Write a short PLAN.md with the pages, components, any library or API you need, and what you are leaving for later. Then build.
2. Put the tool itself on the homepage so a visitor can use it within seconds, with no sign-up. Do the processing in the browser where you can, so it is fast and cheap to run. Look at how Adobe Color, Coolors, Canva Color Palette do it and make ours simpler and faster.
3. Make it rank. Use "color palette extractor" in the title tag, H1 and meta description. Under the tool, add a short how-to and an FAQ with FAQPage schema, and add a sitemap and robots.txt. Scaffold these programmatic pages from one template and a data file: /extract-colors-from-[image-type], /color-palette-for-[design-purpose], /[industry]-color-schemes.
4. Monetisation: Freemium: 20 extractions/day, $5/mo unlimited + export formats. Add a pricing page and the free usage limit, and leave Stripe checkout as a clearly marked stub with the environment variables it needs.
5. Run it locally and test the main flow end to end, including edge cases like empty input and very large files. Fix what breaks, then finish with a summary of what works, what is stubbed and how to deploy it to Vercel.

Paste it into Claude Code in an empty folder. It plans first, so read PLAN.md and steer before it starts building.
