+# Material Color Utilities for Go
+
+Go implementation of Google's Material Color Utilities, which provides algorithms for color extraction and dynamic color in Material Design.
+
+## Installation
+
+```bash
+go get github.com/material-foundation/material-color-utilities/go
+```
+
+## Usage
+
+### HCT Color Space
+
+```go
+import "github.com/material-foundation/material-color-utilities/go/cam"
+
+// Create HCT color from ARGB
+hct := cam.FromInt(0xFF4285F4) // Google Blue
+
+// Access HCT components
+fmt.Printf("Hue: %.2f, Chroma: %.2f, Tone: %.2f\n", hct.Hue, hct.Chroma, hct.Tone)
+
+// Create HCT from components
+hct2 := cam.From(120.0, 50.0, 60.0)
+argb := hct2.ToInt()
+```
+
+### Color Schemes
+
+```go
+import "github.com/material-foundation/material-color-utilities/go/scheme"
+
+// Generate a light scheme from a source color
+lightScheme := scheme.Light(0xFF4285F4)
+
+// Access scheme colors
+fmt.Printf("Primary: %#08x\n", lightScheme.Primary)
+fmt.Printf("Secondary: %#08x\n", lightScheme.Secondary)
+fmt.Printf("Background: %#08x\n", lightScheme.Background)
+```
+
+### Color Harmonization
+
+```go
+import "github.com/material-foundation/material-color-utilities/go/blend"
+
+// Harmonize design color towards theme color
+harmonized := blend.Harmonize(0xFFE91E63, 0xFF4285F4)
+```
+
+### Tonal Palettes
+
+```go
+import "github.com/material-foundation/material-color-utilities/go/palettes"
+
+// Create a tonal palette from a color
+palette := palettes.TonalFromInt(0xFF4285F4)
+
+// Get specific tones
+tone50 := palette.Tone(50)
+tone90 := palette.Tone(90)
+```
+
+### Color Extraction from Images
+
+```go
+import (
+    "image"
+    "image/png"
+    "os"
+    "github.com/material-foundation/material-color-utilities/go/quantize"
+)
+
+// Load an image
+file, _ := os.Open("photo.png")
+defer file.Close()
+img, _ := png.Decode(file)
+
+// Extract pixel data
+pixels := quantize.FromImage(img)
+
+// Or sample every 4th pixel for better performance
+pixels = quantize.FromImageSampled(img, 4)
+
+// Or extract from a specific region
+region := image.Rect(100, 100, 300, 300)
+pixels = quantize.FromImageSubset(img, region)
+
+// Quantize to dominant colors
+quantizer := quantize.NewCelebi()
+colors := quantizer.Quantize(pixels, 16)
+```
+
+## Features
+
+- **HCT Color Space**: A perceptually accurate color space that enables smooth color transitions
+- **Dynamic Color Schemes**: Generate complete Material Design 3 color schemes from a single source color
+- **Color Harmonization**: Blend colors while maintaining visual relationships
+- **Tonal Palettes**: Create tonal variations of colors for consistent design
+- **Quantization**: Extract dominant colors from images
+- **Contrast Utilities**: Calculate and ensure accessible color contrast ratios
