Implement formatter for colored balances

    return format_currency(Decimal(cents) / 100, "EUR", locale="de_DE")

def format_balance(cents: int) -> Text:

    balance = Text(format_euros(cents))

    # TODO Find out why the following behavior occurs and if it is a bug:

    # Interestingly enough, setting style= directly to the same value in the Text constructor causes the

    # balance dialog to use the HTML styles (where the red and green are quite dark), while the data table

    # uses nicer 'theme' colors. With stylize, the theme colors are consistently used.

    balance.stylize("green" if cents > 0 else "red" if cents < 0 else "")

    return balance
