      • getColorName

        public static java.lang.String getColorName​(java.awt.Color c,
                                            java.lang.String defaultName)
        For named colors, returns the name, or 'defaultName' if not a named color. If 'defaultName' is non-null and starts with an uppercase character, the returned name is capitalized (first character uppercase). Use colorToString or colorToString2 to get a String representation (hexadecimal) also for unnamed colors.

      • getColor

        public static java.awt.Color getColor​(java.lang.String name,
                                      java.awt.Color defaultColor)
        For named colors, converts the name String to the corresponding color. Returns 'defaultColor' if the color has no name. Use 'decode' to also decode hex color names like "#ffff00"

      • decode

        public static java.awt.Color decode​(java.lang.String hexColor)
        Converts a String with the color name or the hexadecimal representation of a color with 6 or 8 hex digits to a Color. With 8 hex digits, the first two digits are the alpha. With 6 hex digits, the color is opaque (alpha = hex ff). A hex String may be preceded by '#' such as "#80ff00". When the string does not include a valid color name or hex code, returns Color.GRAY.

      • decode

        public static java.awt.Color decode​(java.lang.String hexColor,
                                    java.awt.Color defaultColor)
        Converts a String with the color name or the hexadecimal representation of a color with 6 or 8 hex digits to a Color. With 8 hex digits, the first two digits are the alpha. With 6 hex digits, the color is opaque (alpha = hex ff). A hex String may be preceded by "#" such as "#80ff00" or "0x". When the string does not include a valid color name or hex code, returns 'defaultColor'.
