1、c++中system(_color )怎样用？-CSDN论坛.html（https://bbs.csdn.net/topics/390758320）

　2.1、

颜色属性由两个十六进制数字指定 -- 第一个为背景，第二个则为前景。每个数字可以为以下任何值之一:

    0 = 黑色       8 = 灰色
    1 = 蓝色       9 = 淡蓝色
    2 = 绿色       A = 淡绿色
    3 = 湖蓝色     B = 淡浅绿色
    4 = 红色       C = 淡红色
    5 = 紫色       D = 淡紫色
    6 = 黄色       E = 淡黄色
    7 = 白色       F = 亮白色
system("color 02");比如这个就是黑底绿字

　2.2、

#include <windows.h>
BOOL SetConsoleColor(WORD color)
{
    HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);
    return SetConsoleTextAttribute(handle, color); // BACKGROUND_BLUE
}
