Iris Laravel Package

Added

• gradient() method to generate color scales between two or more colors (#51)
  • Supports two-color gradients: $colorA->gradient($colorB, $steps)
  • Supports multicolor gradients with pivot colors: $colorA->gradient([$colorB, $colorC], $steps)
  • Works with all color types (Hex, RGB, HSL, HSV, CMYK, OKLCH, etc.)
  • Returns array of colors matching the starting color type

Fixed

• CMYK to RGB conversion now rounds values to produce valid integers
  • Previously, CMYK values that didn't produce clean 0 or 255 RGB values would fail validation

Added

• OKLCH color space support - perceptually uniform color representation
• toOklch() method on all color classes
• Oklch::fromRgb() static factory method for RGB to OKLCH conversion
• clone() method for color objects
• alphaRaw() protected method for internal alpha precision handling
• Comprehensive alpha conversion tests

Fixed

• RGBA to Hexa conversion now preserves original RGB values instead of alpha-compositing (#48)
