FlyColorGenerator class

Generates perceptually uniform, contextually aware 12-step color scales.

The generation process:

1. Converts input colors to OKLCH for perceptual uniformity
2. Finds two closest template scales using ΔE_OK color difference
3. Blends templates using trigonometry to determine mixing ratio
4. Corrects hue and chroma to match source color identity
5. Transposes lightness curve to anchor to background using Bezier easing
6. Generates alpha variants using reverse alpha blending

Usage

import 'package:flycolor/generator.dart';

final colors = FlyColorGenerator.generate(
  appearance: 'light',
  accent: '#3D63DD',
  gray: '#8B8D98',
  background: '#FFFFFF',
);

// Access the generated scales
colors.accentScale;      // 12-step accent scale
colors.grayScale;        // 12-step gray scale
colors.accentScaleAlpha; // Alpha variants
colors.accentContrast;   // Contrast color for text
colors.accentSurface;    // Surface color
