You can change the colors for a console application using Win32 and here's an example on how to:
您可以使用 Win32 更改控制台应用程序的颜色，以下是有关如何操作的示例：
#include "stdafx.h"
#include <Windows.h>
#include <iostream>
using namespace std;
int main(void)
{
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
if (hStdout == INVALID_HANDLE_VALUE)
{
cout << "Error while getting input handle" << endl;
return EXIT_FAILURE;
}
//sets the color to intense red on blue background
SetConsoleTextAttribute(hStdout, FOREGROUND_RED | BACKGROUND_BLUE | FOREGROUND_INTENSITY);
cout << "This is intense red text on blue background" << endl;
//reverting back to the normal color
SetConsoleTextAttribute(hStdout, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);
return EXIT_SUCCESS;
}
Look at the MSDN documentation for the SetConsoleTextAttributefunction and Console Screen Buffersfor more information.
有关更多信息，请查看该SetConsoleTextAttribute函数的 MSDN 文档和控制台屏幕缓冲区。
A more complete example on console applications using Win32 is available here.

Colour isn't a C++ thing, but a property of your terminal. If your terminal speaks ANSI (e.g. any Linux terminal, or DOS or Windows NT if you add DEVICE=C:\DOS\ansi.systo your config.sys, or later Windows if you call the shell with cmd.exe /kansicon), then you can try the following gimmick:
颜色不是 C++ 的东西，而是终端的属性。如果您的终端使用 ANSI（例如，任何 Linux 终端，或 DOS 或 Windows NT，如果您添加DEVICE=C:\DOS\ansi.sys到您的config.sys，或更高版本的 Windows，如果您使用 调用外壳cmd.exe /kansicon），那么您可以尝试以下噱头：
#define ANSI_COLOR_RED "\x1b[31m"
#define ANSI_COLOR_GREEN "\x1b[32m"
#define ANSI_COLOR_YELLOW "\x1b[33m"
#define ANSI_COLOR_BLUE "\x1b[34m"
#define ANSI_COLOR_MAGENTA "\x1b[35m"
#define ANSI_COLOR_CYAN "\x1b[36m"
#define ANSI_COLOR_BRIGHT "\x1b[1m"
#define ANSI_COLOR_RESET "\x1b[0m"
std::cout << ANSI_COLOR_RED "Hello World\n" ANSI_COLOR_RESET;
Wikipedia has a list of ANSI escape sequences.
维基百科有一个ANSI 转义序列列表。

I believe that you are looking for the SetConsoleTextAttributefunction. The first parameter, hConsoleOutput, would be the standard output handle obtained via GetStdHandle(STD_OUTPUT_HANDLE). The second parameter is a bitwise-OR (|) combination of the desired character attributes.
我相信您正在寻找该SetConsoleTextAttribute功能。第一个参数hConsoleOutput将是通过 获得的标准输出句柄GetStdHandle(STD_OUTPUT_HANDLE)。第二个参数是|所需字符属性的按位或 ( ) 组合。
