Sip is a paid Mac menu bar app for picking, organizing, and sharing colors, built around a persistent color dock that stays visible on screen edges while working in other apps.
Smart Formats auto-detect which app is active and adjust the copied color format to match, and a built-in contrast checker includes a one-click fix that adjusts brightness, hue, or saturation until the pairing passes, saving a trip to a separate contrast tool.
Mac users who pick and reuse colors often enough across projects to want a persistent, always-visible color dock instead of reopening a picker each time.
It's a one-time $20 purchase with a 15-day full-featured trial, not a subscription, worth noting before assuming it's free like most browser-based pickers.
