wide_color_tool

A comprehensive color manipulation library for Flutter, providing extensive functionality for working with colors in various color spaces.

Features

• Support for multiple color spaces: RGB, HSV, HSL, and CMYK
• Easy conversion between color spaces
• Color mixing and blending
• Contrast calculation and adjustment
• Luminance calculation
• Opacity and alpha channel manipulation
• Flexible color creation methods

Getting Started

Add this package to your pubspec.yaml:

dependencies:
  wide_color: ^1.0.1

Then run: flutter pub get

Usage Creating Colors

final red = WideColor.fromRGB(255, 0, 0);

final green = WideColor.fromHSV(120, 1.0, 1.0);

final blue = WideColor.fromHSL(240, 1.0, 0.5);

final yellow = WideColor.fromCMYK(0.0, 1.0, 1.0, 0.0);

final magenta = WideColor.fromString("#FF00FF");

Color Space Conversions

final purple = WideColor.fromRGB(128, 0, 128);

print(purple.hsv);  // HSVColor
print(purple.hsl);  // HSLColor
print(purple.cmyk);  // CMYKColor

Color Manipulation

final color = WideColor.fromRGB(100, 150, 200);

// Adjust individual components
final lighterColor = color.withValue(0.8);
final moreSaturated = color.withSaturationV(0.9);
final redder = color.withRed(220);

// Mix colors
final mixedColor = color.mix(WideColor.fromRGB(200, 100, 50), otherInfluence: 0.3);

Contrast and Accessibility

final backgroundColor = WideColor.fromRGB(240, 240, 240);
final textColor = WideColor.fromRGB(50, 50, 50);

// Calculate contrast ratio
final contrastRatio = backgroundColor.contrast(textColor);

// Ensure minimum contrast
final adjustedTextColor = backgroundColor.fixContrast(
  textColor,
  minContrast: 4.5,
  preference: ContrastPreference.dark,
);

Advanced Usage The library provides two main classes:

• WideColor: An immutable color representation for efficient storage and calculations.
• ToolColor: A mutable color class for interactive color manipulation.
