## What it is
Pika is a free, open-source, native macOS colour picker app built with Swift and SwiftUI. It lets users pick colours from anywhere on screen, copy them in multiple formats, and check WCAG/APCA contrast compliance.

## Use cases
- pick a colour from anywhere on my screen on mac
- copy hex or rgb values of onscreen colours
- check contrast ratio for wcag compliance between two colours
- convert colours between hex, rgb, hsl, lab and oklch formats
- automate colour picking from scripts via url scheme
- keep a history of colours I've picked

## When to choose
- you're a designer or developer on macOS who needs fast screen colour picking
- you need multiple colour formats and clipboard copying
- you want accessibility-focused contrast checking (WCAG/APCA)
- you prefer open-source, native, keyboard-driven tools

## When to avoid
- you're on Windows or Linux
- you need a full design suite or palette management tool
- you need to pick colours on iOS or from a browser only
