Add color for success and error messages

[aj3sh]

Adding color to CLI messages would be helpful for users to distinguish between error, success, or normal messages. Let's attempt to implement this without using any additional dependencies initially; if that's not possible, we can explore and discuss the packages to use.

Here is my POC for the color message (tested on Mac's terminal and iterm):

import sys
from typing import List, Union

class Styles:
    RESET = "\033[0m"
    BOLD = "\033[1m"
    UNDERLINE = "\033[4m"
    ITALIC = "\033[3m"
    SELECTED = "\033[7m"

    BLACK = "\033[30m"
    GREY = "\33[90m"
    CYAN = "\033[96m"
    RED = "\033[91m"
    GREEN = "\033[92m"
    BLUE = "\033[34m"
    YELLOW = "\033[93m"
    MAGENTA = "\033[35m"
    WHITE = "\033[37m"

class StyledText:
    def __init__(self, text: str, style: Union[str, List[str]]):
        self.text = text
        self.styles = style if isinstance(style, List) else [style]

        # creating styled text
        joined_styles = "".join(self.styles)
        self._styled_text = f"{joined_styles}{text}{Styles.RESET}"

    def __str__(self) -> str:
        return self._styled_text

    def __repr__(self) -> str:
        return self._styled_text

sys.stdout.write(str(StyledText("I am red.\n", Styles.RED)))
sys.stdout.write(str(StyledText("I am green.\n", Styles.GREEN)))
sys.stdout.write(str(StyledText("I am underlined.\n", Styles.UNDERLINE)))
sys.stdout.write(
    str(StyledText("I am italic and blue.\n", [Styles.UNDERLINE, Styles.BLUE]))
)
sys.stdout.write(
    str(StyledText("I am yellow selected.\n", [Styles.SELECTED, Styles.YELLOW]))
)

Tested on Windows 11 Command Prompt, Power Shell, and Git bash: Working fine. Tested on Windows 10 Command Prompt: Not working (displays the color character \033[0m).
