A1 Color Picker 作成者: A1 Local Extensions

A1 Color Picker is a simple local color utility for designers, developers, marketers, and site owners. Click Pick color, choose a pixel with the browser eyedropper where available, and copy the value you need. In Firefox, the extension uses a current-tab preview fallback so you can sample a pixel from the active page.

The extension supports HEX, RGB, and HSL formats. It also keeps a local history so recently used colors are easy to copy again. Picked colors and page previews stay on the device and are not uploaded.

Key features:
- On-screen eyedropper.
- Current-tab preview fallback for browsers without a native eyedropper.
- HEX, RGB, and HSL conversion.
- Local color history.
- Manual HEX entry.
- Palette copy for design notes.
