如何使用python中的输入访问枚举成员？

from enum import Enum

class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3

input_color = input("请输入颜色（红/绿/蓝）：")

if input_color == "红":
    selected_color = Color.RED
elif input_color == "绿":
    selected_color = Color.GREEN
elif input_color == "蓝":
    selected_color = Color.BLUE
else:
    print("无效的颜色输入！")

color_mapping = {
    "红": Color.RED,
    "绿": Color.GREEN,
    "蓝": Color.BLUE
}
selected_color = color_mapping.get(input_color, None)
if selected_color is None:
    print("无效的颜色输入！")

if selected_color:
    print("选择的颜色为：", selected_color.name)
    print("颜色的值为：", selected_color.value)
