ChromaWild: A Local Gemma-Powered Color Walk

说明与用途

ChromaWild 是一个本地 Web 应用，使用 Gemma 通过 Ollama 生成户外颜色探索任务，帮助用户在日常公共空间中寻找并比较颜色，并记录观察笔记。

问题

Users want a simple way to generate outdoor color exploration prompts that reflect real walking environments without relying on paid inference APIs.

结果

ChromaWild enables users to generate context‑aware color exploration quests locally, avoiding external API costs and allowing experimentation with different models.

• Request a new quest from the browser
• Next.js API route sends a prompt to local Ollama
• Ollama returns a JSON with title, color, subject, hint
• API validates the fields and hex value
• Browser displays the quest and allows color comparison, note taking, and sketching
• All data is stored in browser local storage
