ColorStation EN

ColorStation is a performance-first color picker extension for Microsoft Edge (Manifest V3).

It starts instantly from the toolbar, samples visible pixels using viewport capture, and provides a precision loupe workflow with persistent local history.

Key Features
Direct action UX: click extension icon -> picker starts immediately (no popup gate).
Precision overlay:
reticle + loupe
live HEX / RGB / HSL readout
sampling modes 1x1, 3x3, 5x5, 11x11, 25x25
Adaptive capture strategy:
robust viewport sampling with chrome.tabs.captureVisibleTab
adaptive recapture for moving surfaces (video/canvas/animated image targets)
Strong copy confirmation and post-pick actions (Pick again, History, Exit).
Local-first storage (no telemetry, no external API calls).
Persistent history limited to the latest 5 colors.

How It Works
User triggers picker from toolbar icon or command (Alt+Shift+C).
Background worker ensures content script is present on the active tab.
Content script enters pick mode and captures visible tab for sampling.
Pointer movement updates reticle/loupe and reads pixel color from the latest capture buffer.
On click, color is copied and saved to local history, then post-pick controls appear.
