Pika

An open-source color picker for macOS: pick from anywhere on screen, check WCAG and APCA contrast, and copy in seven formats including OKLCH. Free, or $2.99 on the Mac App Store.

• Picks colors from anywhere on screen
• Checks contrast with WCAG and APCA together
• Copies Hex, RGB, HSL, LAB, OKLCH and more
• Menu bar, Dock or popover, with a global hotkey
• Free and open source (MIT)

• Window shadow control: keep it, hide it while picking or turn it off

• Long color values scale down to stay on two lines
• Light mode polish for the footer, palettes and dividers
• The window outline no longer stretches when dragged to the top
