+
+`ColorMacros` is a bundle of expression macros that turn the color tokens you copy from
+Figma/Sketch into compile-time `SwiftUI.Color` literals:
+
+```swift
+import SwiftUI
+import ColorMacros
+
+let brand = #Color(hex: "#FF9900")
+let overlay = #Color(hex: "0x336699CC")
+let grass = #Color(rgba: 154, 234, 98, 1)
+let warning = #Color(hsla: 32, 100, 50, 0.8)
+let accent = #Color(hsba: 200, 60, 80, 0.65)
+```
+
+## Features
+
+- `hex:` accepts `RGB`, `RGBA`, `RRGGBB`, `RRGGBBAA`, with or without `#` or a `0x` prefix.
+- `rgb:` / `rgba:` accept 0–255 integer channels, optionally plus opacity (0–1).
+- `hsl:` / `hsla:` accept degrees/percentages, matching what design tools output.
+- `hsb:` / `hsba:` cover hue–saturation–brightness (%), again with optional opacity.
+- Every variant emits a `SwiftUI.Color` literal (no runtime helpers) and validates inputs at build time.
+
+Example diagnostic:
+
+```
+#Color(hex: "#12345")
+            ┬───────
+            ╰─ 🛑 Hex literals must contain 3, 4, 6, or 8 digits, but found 5.
+```
+
+## Installation
+
+Add the package to your project:
+
+```swift
+dependencies: [
+  .package(url: "https://github.com/davdroman/swiftui-color-macros.git", from: "0.1.0")
+],
+targets: [
+  .target(
+    name: "App",
+    dependencies: [
+      .product(name: "ColorMacros", package: "swiftui-color-macros")
+    ]
+  )
+]
+```
+
+Then import the module alongside SwiftUI wherever you need the macro.
