Color

The Color value object represents a color in hexadecimal format (#RRGGBB). It provides methods for:

• Converting to RGB components
• Adding an alpha channel
• Determining if a color is dark
• Inverting a color

Usage

// Create a new color
color, err := appearance.NewColor("#FF5733")
if err != nil {
    // Handle error
}

// Get RGB components
r, g, b, err := color.RGB()
if err != nil {
    // Handle error
}

// Check if color is dark
isDark, err := color.IsDark()
if err != nil {
    // Handle error
}

// Invert the color
inverted, err := color.Invert()
if err != nil {
    // Handle error
}

// Add alpha channel
colorWithAlpha, err := color.WithAlpha(128) // 50% opacity
if err != nil {
    // Handle error
}
