使用 SetConsoleTextAttribute(HANDLE hConsoleOutput,WORD wAttributes);

SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_RED |FOREGROUND_GREEN | FOREGROUND_BLUE);可以更改为白色

FOREGROUND_RED 红色

FOREGROUND_GREEN绿色

FOREGROUND_BLUE蓝色

用|相加颜色

#include <iostream>
#include <windows.h>
using namespace std;

int main()
{
	cout << "原色testCOLOR（没有设置字体颜色）" << endl;
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_RED |
		FOREGROUND_GREEN | FOREGROUND_BLUE);//设置三色相加
	cout << "白色testCOLOR（红色绿色蓝色相加）" << endl;
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_RED);
	//设置红色
	cout << "红色testCOLOR（设置的颜色为红色）" << endl;
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY | FOREGROUND_GREEN);
	//设置绿色

	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY);
	//设置颜色，没有添加颜色，故为原色
	cout << endl;
