    public static final String CYAN_BOLD = "\033[1;36m";   // CYAN
    public static final String WHITE_BOLD = "\033[1;37m";  // WHITE

    // Underline
    public static final String BLACK_UNDERLINED = "\033[4;30m";  // BLACK

    public static final String PURPLE_UNDERLINED = "\033[4;35m"; // PURPLE
    public static final String CYAN_UNDERLINED = "\033[4;36m";   // CYAN
    public static final String WHITE_UNDERLINED = "\033[4;37m";  // WHITE

    // Background
    public static final String BLACK_BACKGROUND = "\033[40m";  // BLACK
    public static final String RED_BACKGROUND = "\033[41m";    // RED
    public static final String GREEN_BACKGROUND = "\033[42m";  // GREEN
    public static final String YELLOW_BACKGROUND = "\033[43m"; // YELLOW

    public static final String PURPLE_BACKGROUND = "\033[45m"; // PURPLE
    public static final String CYAN_BACKGROUND = "\033[46m";   // CYAN
    public static final String WHITE_BACKGROUND = "\033[47m";  // WHITE

    // High Intensity
    public static final String BLACK_BRIGHT = "\033[0;90m";  // BLACK
    public static final String RED_BRIGHT = "\033[0;91m";    // RED
    public static final String GREEN_BRIGHT = "\033[0;92m";  // GREEN

    // Bold High Intensity
    public static final String BLACK_BOLD_BRIGHT = "\033[1;90m"; // BLACK
    public static final String RED_BOLD_BRIGHT = "\033[1;91m";   // RED
    public static final String GREEN_BOLD_BRIGHT = "\033[1;92m"; // GREEN
    public static final String YELLOW_BOLD_BRIGHT = "\033[1;93m";// YELLOW
    public static final String BLUE_BOLD_BRIGHT = "\033[1;94m";  // BLUE
    public static final String PURPLE_BOLD_BRIGHT = "\033[1;95m";// PURPLE
    public static final String CYAN_BOLD_BRIGHT = "\033[1;96m";  // CYAN
    public static final String WHITE_BOLD_BRIGHT = "\033[1;97m"; // WHITE

    // High Intensity backgrounds
    public static final String BLACK_BACKGROUND_BRIGHT = "\033[0;100m";// BLACK
    public static final String RED_BACKGROUND_BRIGHT = "\033[0;101m";// RED
    public static final String GREEN_BACKGROUND_BRIGHT = "\033[0;102m";// GREEN
    public static final String YELLOW_BACKGROUND_BRIGHT = "\033[0;103m";// YELLOW

    public static final String PURPLE_BACKGROUND_BRIGHT = "\033[0;105m"; // PURPLE
    public static final String CYAN_BACKGROUND_BRIGHT = "\033[0;106m";  // CYAN
    public static final String WHITE_BACKGROUND_BRIGHT = "\033[0;107m";   // WHITE
}

Example 2: java console text color

// Define color constants
public static final String TEXT_RESET = "\u001B[0m";
public static final String TEXT_BLACK = "\u001B[30m";
public static final String TEXT_RED = "\u001B[31m";
public static final String TEXT_GREEN = "\u001B[32m";
public static final String TEXT_YELLOW = "\u001B[33m";
public static final String TEXT_BLUE = "\u001B[34m";
public static final String TEXT_PURPLE = "\u001B[35m";
public static final String TEXT_CYAN = "\u001B[36m";
public static final String TEXT_WHITE = "\u001B[37m";

// Implementation
System.out.println(TEXT_RED + "This text is red!" + TEXT_RESET);
