OkColor

A Flutter package for working with colors in the Oklab color space, providing utilities for color manipulation, conversion, and analysis.

Features

• Convert between RGB, HSV, HSL, and Oklab color spaces
• Perform color manipulations like lightening, darkening, and saturation adjustments
• Generate color palettes and gradients
• Gamut mapping and clipping functions

Getting started

Add okcolor to your pubspec.yaml file:

dependencies:
  okcolor: ^1.0.0

Then run dart pub get or flutter pub get.

Usage

Here are some examples demonstrating how to use the OkColor package:

Converting between color spaces

import 'package:flutter/material.dart';
import 'package:okcolor/okcolor.dart';

void main() {
  // Convert from Color to OkLab
  Color color = Colors.blue;
  OkLab oklab = OkLab.fromColor(color);
  // Convert from OkLab back to Color
  Color convertedColor = oklab.toColor();
  // Convert from Color to OkHsv
  OkHsv okhsv = OkHsv.fromColor(color);
}

Interpolating between colors

import 'package:flutter/material.dart';
import 'package:okcolor/okcolor.dart';

void main() {
  Color startColor = Colors.red;
  Color endColor = Colors.blue;
  double fraction = 0.5;
  
  // Interpolate using OkLab color space
  Color interpolatedColor = interpolate(
    startColor, 
    endColor, 
    fraction,
    method: InterpolationMethod.oklab
  );

  // Interpolate using OkHSV color space
  Color interpolatedColorHSV = interpolate(
    startColor, 
    endColor, 
    fraction,
    method: InterpolationMethod.okhsv
  );
}
