要在Airflow中实现彩色日志记录，可以按照以下步骤进行操作：

1. 安装依赖库：

   pip install colorlog
   

2. 创建一个自定义的日志处理器（ColoredStreamHandler）来格式化和输出彩色日志：

   import logging
   from colorlog import ColoredFormatter
   
   class ColoredStreamHandler(logging.StreamHandler):
       def __init__(self):
           super().__init__()
           self.setFormatter(ColoredFormatter(
                "%(log_color)s%(levelname)s:%(name)s:%(message)s",
                log_colors={
                    'DEBUG': 'green',
                    'INFO': 'blue',
                    'WARNING': 'yellow',
                    'ERROR': 'red',
                    'CRITICAL': 'red,bg_white',
                },
                secondary_log_colors={},
                style='%'
           ))
   

3. 在Airflow的dag文件中，设置日志处理器为ColoredStreamHandler：

   import logging
   from airflow import DAG
   from airflow.operators.python_operator import PythonOperator
   
   default_args = {
       'owner': 'airflow',
       'start_date': datetime(2022, 1, 1),
   }
   
   dag = DAG('example_dag', default_args=default_args)
   
   def my_task():
       logging.debug('This is a debug message')
       logging.info('This is an info message')
       logging.warning('This is a warning message')
       logging.error('This is an error message')
       logging.critical('This is a critical message')
   
   task = PythonOperator(
       task_id='my_task',
       python_callable=my_task,
       dag=dag
   )
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime.timedelta(minutes=60)
   
   task.dag.dagrun_timeout = datetime
