| isFullyOpaque() | Indicates if this color is fully opaque (alpha == 255) |
| isTranslucent() | Indicates if this color is translucent (alpha between 1 and 254) |
| getBrightness() | Calculates brightness/lightness of the color (HSL model). |
| getHue() | Calculates hue of the color in degrees [0..360]. |

| toRGB() | Serializes this instance to CSS rgb() string notation (without alpha). |
| toHexRGBA() | Serializes this instance to hexadecimal #RRGGBBAA notation. |
| toHexRGB() | Serializes this instance to hexadecimal #RRGGBB notation (without alpha). |
| toString() | Returns the string representation using the most appropriate CSS notation. |
| equals(Object obj) | Equality comparison with another Argb32Color. |
| hashCode() | |
| equals(Argb32Color other) | Compares this color with another Argb32Color. |
| equals(Rgb24Color other) | Compares this color with a Rgb24Color. |
| toRgb24Color() | Cast this Argb32Color to Rgb24Color, losing alpha channel. |
| fromRgb24Color(Rgb24Color rgbColor) | Create Argb32Color from Rgb24Color with alpha set to 255. |
