Вы можете использовать словарь, как показано ниже в коде, а затем цикл:
Dictionary<int, KeyValuePair<string, ConsoleColor>> keyValuePairs = new Dictionary<int, KeyValuePair<string, ConsoleColor>>();
keyValuePairs.Add(1, new KeyValuePair<string, ConsoleColor>("my blue text", ConsoleColor.Blue));
keyValuePairs.Add(2, new KeyValuePair<string, ConsoleColor>("my red text", ConsoleColor.Red));
foreach (var keyItem in keyValuePairs.Keys)
{
ConsoleColor color = keyValuePairs[keyItem].Value;
string textTobeDisplayed = keyValuePairs[keyItem].Key;
Console.ForegroundColor = color;
Console.Write(textTobeDisplayed);
}
