Full Changelog: 4.1.1...4.1.2

Fixes incorrect param type for PHPStan.

Added gradient() method for generating color scales (#51, #50)

• Supports two-color gradients: $colorA->gradient($colorB, $steps)
• Supports multi-color gradients with pivots: $colorA->gradient([$colorB, $colorC], $steps)
• Works with all color types (Hex, RGB, HSL, HSV, CMYK, OKLCH, RGBA, HSLA)
• Returns array of colors matching the starting color type
• Added comprehensive tests for all color types and edge cases

Fixed OKLCH parsing, accepting both comma and space separated formats.

• Support CSS Color Level 4 space-separated syntax: oklch(40.1% 0.123 21.57)
• Continue supporting comma-separated syntax: oklch(70%, 0.15, 150)
• Alpha values in input are parsed but ignored (e.g., oklch(50% 0.1 180 / .5))

A major release bringing modern PHP support and a new color space. This version requires PHP 8.1+ and introduces OKLCH, a perceptually uniform color space, which is ideal for creating accessible color palettes and smooth gradients.
