我正在尝试使文本淡入淡出，但它所做的只是提供有关超出范围的错误消息。我被告知使用colormode（255），但它不起作用。我不确定255是高还是高，但请帮忙。

我测试了你的代码，它在使用Turtle 0.0.2的Python 2.7.10环境中工作正常。

我认为你的问题是你在x/5中传递了FADE_IN_OUT参数，你必须使用python 3.你得到的错误，

_tkinter.TclError: expected integer but got "200.0"

抱怨接收浮点而不是整数。尝试使用Python 3的整数除法运算符//而不是单个/。

例如，像这样呼叫FADE_IN_OUT：

 FADE_IN_OUT("47 Studios", "center", "Arial", x//5, "normal", 2.5, 2.5, 5)

或者，尝试在Python 2中运行代码。

python turtle colormode无法正常工作
