1.改变整个控制台的颜色
用 system("color 0A");
其中color后面的0是背景色代号，A是前景色代号。各颜色代码如下：
0=黑色
1=蓝色
2=绿色
3=湖蓝色
4=红色
5=紫色
6=黄色
7=白色
8=灰色
9=淡蓝色
A=淡绿色
B=淡浅绿色
C=淡红色
D=淡紫色
E=淡黄色
F=亮白色
2.改变下一个输出或者输入字体和背景的颜色

采用SetConsoleTextAttribute函数，如
White on Black：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);
Red on Black：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
FOREGROUND_RED);
Green on Black：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
FOREGROUND_GREEN);
Yellow on Black：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
FOREGROUND_RED | FOREGROUND_GREEN);
Blue on Black：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
FOREGROUND_BLUE);
Magenta on Black：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
FOREGROUND_RED | FOREGROUND_BLUE);
Cyan on Black：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
FOREGROUND_GREEN | FOREGROUND_BLUE);
Black on Gray：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |
BACKGROUND_INTENSITY);
Black on White：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |
FOREGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE);
Red on White：
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |
FOREGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE |
FOREGROUND_RED);
等等。
需要引入头文件：
windows.h
函数原型：
BOOL SetConsoleTextAttribute( HANDLE hConsoleOutput, WORD wAttributes );
wAttributes 的取值含义对应如下：
Attribute Meaning
FOREGROUND_BLUE Text color contains blue.
FOREGROUND_GREEN Text color contains green.
FOREGROUND_RED Text color contains red.
FOREGROUND_INTENSITY Text color is intensified.
BACKGROUND_BLUE Background color contains blue.
BACKGROUND_GREEN Background color contains green.
BACKGROUND_RED Background color contains red.
BACKGROUND_INTENSITY Background color is intensified.
COMMON_LVB_LEADING_BYTE Leading byte.
COMMON_LVB_TRAILING_BYTE Trailing byte.
COMMON_LVB_GRID_HORIZONTAL Top horizontal.
COMMON_LVB_GRID_LVERTICAL Left vertical.
COMMON_LVB_GRID_RVERTICAL Right vertical.
COMMON_LVB_REVERSE_VIDEO Reverse foreground and background attributes.
COMMON_LVB_UNDERSCORE Underscore.
