首先，在已經下載好的python文件目錄下，找到config-highlight.def文件，我的是在H:\python\python3**\Lib\idlelib**文件夾下。

打開文件后，你會看到一些默認的顏色配置，比如經典的顏色配置就是白色背景，一般這個文件中會有兩種配置可供選擇：

[IDLE Classic]和 [IDLE New]，表現在IDLE界面上就是在python shell下，選擇options—configure IDLE—-highlighting選項中，右側的highlighting theme主題選擇，有兩種可選方案。

如果直接在源文件上修改顏色有些麻煩，除非你特別熟悉顏色。網上有經典的背景配置：[Obsidian]

definition-foreground = #678CB1

error-foreground = #FF0000

string-background = #293134

keyword-foreground = #93C763

normal-foreground = #E0E2E4

comment-background = #293134

hit-foreground = #E0E2E4

builtin-background = #293134

stdout-foreground = #678CB1

cursor-foreground = #E0E2E4

break-background = #293134

comment-foreground = #66747B

hilite-background = #2F393C

hilite-foreground = #E0E2E4

definition-background = #293134

stderr-background = #293134

hit-background = #000000

console-foreground = #E0E2E4

normal-background = #293134

builtin-foreground = #E0E2E4

stdout-background = #293134

console-background = #293134

stderr-foreground = #FB0000

keyword-background = #293134

string-foreground = #EC7600

break-foreground = #E0E2E4

error-background = #293134

[tango]

definition-foreground = #fce94f

error-foreground = #fa8072

string-background = #2e3436

keyword-foreground = #8cc4ff

normal-foreground = #ffffff

comment-background = #2e3436

hit-foreground = #ffffff

break-foreground = #000000

builtin-background = #2e3436

stdout-foreground = #eeeeec

cursor-foreground = #fce94f

hit-background = #2e3436

comment-foreground = #73d216

hilite-background = #edd400

definition-background = #2e3436

stderr-background = #2e3436

break-background = #2e3436

console-foreground = #87ceeb

normal-background = #2e3436

builtin-foreground = #ad7fa8

stdout-background = #2e3436

console-background = #2e3436

stderr-foreground = #ff3e40

keyword-background = #2e3436

string-foreground = #e9b96e

hilite-foreground = #2e3436

error-background = #2e3436

直接把上面的代碼copy到剛才打開的config-highlight.def文件中，然后重啟shell就可以。

重啟后，shell會默認選擇原來的。你就在highlighting theme主題中查看，此時已經多了兩種主題，就是你剛才添加的。
