【问题描述】：

我的问题如下图所示。我想更改下图中红色矩形指定的代码区域的突出显示颜色样式。但我不知道我应该改变哪个令牌的样式。

我的pygment风格设置代码如下

from pygments.style import Style
from pygments.token import Keyword, Name, Comment, String, Error, \
     Number, Operator, Generic, Whitespace, Token


class EmacsStyle(Style):
    """
    The default style (inspired by Emacs 22).
    """

    background_color = "#333333"
    highlight_color = "#a7a695"
    default_style = ""

    styles = 
        Token:                     "#ffffff",
        Whitespace:                "#bbbbbb",
        Comment:                   "italic #008800",
        Comment.Preproc:           "noitalic",
        Comment.Special:           "noitalic bold",

        Keyword:                   "bold #B541FF",
        Keyword.Pseudo:            "nobold",
        Keyword.Type:              "bold #00BB00",

        Operator:                  "#666666",
        Operator.Word:             "bold #AA22FF",

        Name.Builtin:              "#B541FF",
        Name.Function:             "#00A000",
        Name.Class:                "#4242FF",
        Name.Namespace:            "bold #4242FF",
        Name.Exception:            "bold #D2413A",
        Name.Variable:             "#B8860B",
        Name.Constant:             "#880000",
        Name.Label:                "#A0A000",
        Name.Entity:               "bold #999999",
        Name.Attribute:            "#BB4444",
        Name.Tag:                  "bold #008000",
        Name.Decorator:            "#AA22FF",

        String:                    "#BB4444",
        String.Doc:                "italic",
        String.Interpol:           "bold #BB6688",
        String.Escape:             "bold #BB6622",
        String.Regex:              "#BB6688",
        String.Symbol:             "#B8860B",
        String.Other:              "#008000",
        Number:                    "#666666",

        Generic.Heading:           "bold #4242FF",
        Generic.Subheading:        "bold #B541FF",
        Generic.Deleted:           "#D2413A",
        Generic.Inserted:          "#00A000",
        Generic.Error:             "#FF0000",
        Generic.Emph:              "italic",
        Generic.Strong:            "bold",
        Generic.Prompt:            "bold #4242FF",
        Generic.Output:            "#888",
        Generic.Traceback:         "#04D",

        Error:                     "border:#FF0000"
    

【问题讨论】：

该代码在内核中被高亮显示，而特定的高亮部分尚未由 pygments 完成，因此无法轻松配置。

【参考方案1】：

我发现了一个 IPython 魔术命令来改变颜色（在 Mac 上）：

%colors NoColor

或（在 Linux 上）

%colors Linux

这不是一个完美的解决方案，但有效。
