Color Conversion Library

Go language-based color model conversion library that supports mutual conversion between multiple color formats, compliant with W3C color specifications.

Core Features

• Supports RGB/RGBA, HEX, HSL/HSLA, HSV, CMYK color models
• Provides unified interface Color for color operations (see interface.go)
• Precision assurance: Color values use uint8/uint16, opacity uses float32
• Error handling: All parsing functions return (result, error)

Installation

go get github.com/zjhsd2007/color

Usage Example

package main

import (
	"github.com/zjhsd2007/color"
)

func main() {
	hex, _ := color.StrToHex("#ff0000")
	rgb, _ := hex.ToRGB()
	rgbStr := rgb.String() // "rgb(255,0,0)"
}

Design Characteristics

• Performance optimization: Avoid redundant calculations, integer operations take precedence over floating-point operations
• Extensibility: Modular design allows adding new color models by implementing base interface
• Test coverage: Comprehensive unit tests verify conversion accuracy (see color_test.go)
