正如其他人所述,您可以使用转义字符。 你可以使用我的标题,以使它更容易:
#ifndef _COLORS_
#define _COLORS_
/* FOREGROUND */
#define RST "\x1B[0m"
#define KRED "\x1B[31m"
#define KGRN "\x1B[32m"
#define KYEL "\x1B[33m"
#define KBLU "\x1B[34m"
#define KMAG "\x1B[35m"
#define KCYN "\x1B[36m"
#define KWHT "\x1B[37m"
#define FRED(x) KRED x RST
#define FGRN(x) KGRN x RST
#define FYEL(x) KYEL x RST
#define FBLU(x) KBLU x RST
#define FMAG(x) KMAG x RST
#define FCYN(x) KCYN x RST
#define FWHT(x) KWHT x RST
#define BOLD(x) "\x1B[1m" x RST
#define UNDL(x) "\x1B[4m" x RST
#endif /* _COLORS_ */
使用header的宏的一个例子可以是:
#include <iostream>
#include "colors.h"
using namespace std;
int main()
{
cout << FBLU("I'm blue.") << endl;
cout << BOLD(FBLU("I'm blue-bold.")) << endl;
return 0;
}

这是一个老主题,但我编写了一个类,其中包含嵌套子类和由简单C宏定义的颜色静态成员。
我在dreamincode.net中通过用户no2pencil从这篇文章中获得了颜色函数。
我这样做是为了能够像这样使用std::cout流中的静态常量:
cout << zkr::cc::fore::red << "This is red text. "
<< zkr::cc::console << "And changing to console default colors, fg, bg."
<< endl;
类和测试程序的源代码可以在这里下载。
cc::console将重置为控制台默认颜色和属性,cc::underline将为文本下划线,这在putty上工作,我已经测试了测试程序。
颜色:
black
blue
red
magenta
green
cyan
yellow
white
lightblack
lightblue
lightred
lightmagenta
lightgreen
lightcyan
lightyellow
lightwhite
它可以用于cc静态类的前静态和后静态子类。

为了更实用,我在这里添加了类代码。
颜色代码宏:
#define CC_CONSOLE_COLOR_DEFAULT "\033[0m"
#define CC_FORECOLOR(C) "\033[" #C "m"
#define CC_BACKCOLOR(C) "\033[" #C "m"
#define CC_ATTR(A) "\033[" #A "m"
main color函数定义屏幕的颜色或属性:
char *cc::color(int attr, int fg, int bg)
{
static char command[13];
/* Command is the control command to the terminal */
sprintf(command, "%c[%d;%d;%dm", 0x1B, attr, fg + 30, bg + 40);
return command;

最好的方法是使用ncurses库——尽管如果你只是想输出一个简单的彩色字符串,这可能是一个大锤来敲坚果
你可以使用ANSI颜色代码。
使用这些函数。
enum c_color{BLACK=30,RED=31,GREEN=32,YELLOW=33,BLUE=34,MAGENTA=35,CYAN=36,WHITE=37};
enum c_decoration{NORMAL=0,BOLD=1,FAINT=2,ITALIC=3,UNDERLINE=4,RIVERCED=26,FRAMED=51};
void pr(const string str,c_color color,c_decoration decoration=c_decoration::NORMAL){
cout<<"\033["<<decoration<<";"<<color<<"m"<<str<<"\033[0m";
}
void prl(const string str,c_color color,c_decoration decoration=c_decoration::NORMAL){
cout<<"\033["<<decoration<<";"<<color<<"m"<<str<<"\033[0m"<<endl;
}
在你输出任何你需要的颜色之前,确保你在一个终端:
[ -t 1 ] && echo 'Yes I am in a terminal' # isatty(3) call in C
然后你需要检查终端能力,如果它支持颜色
在使用terminfo(基于Linux)的系统上,您可以获得支持的颜色数量为
Number_Of_colors_Supported=$(tput colors)
在使用termcap(基于BSD)的系统上,您可以获得支持的颜色数量为
Number_Of_colors_Supported=$(tput Co)
然后做出决定:
[ ${Number_Of_colors_Supported} -ge 8 ] && {
echo 'You are fine and can print colors'
} || {
echo 'Terminal does not support color'
}
顺便说一下,不要像之前建议的那样使用ESC字符着色。 使用标准的终端调用功能,将为您指定特定终端支持的正确颜色。

试试我的标题这里一个快速和简单的方法来着色文本:Aedi的颜色标题
Escape-Sequence-Color-Header
在Unix中使用c++为输出着色!!
文本属性选项:
ATTRIBUTES_OFF, BOLD, UNDERSCORE, BLINK, REVERSE_VIDEO, CONCEALED
颜色选择:
BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE
格式:
通用格式,在$变量$中包含你想要的值
COLOR_$Foreground_Color$_$Background_Color$
COLOR_$Text_Attribute$_$Foreground_Color$_$Background_Color$
COLOR_NORMAL // To set color to default
e.g.
COLOR_BLUE_BLACK // Leave Text Attribute Blank if no Text Attribute appied
COLOR_UNDERSCORE_YELLOW_RED
COLOR_NORMAL
用法:
只是使用流的颜色,你想在输出文本和 在输出文本后再次使用以将颜色设置为正常。
cout << COLOR_BLUE_BLACK << "TEXT" << COLOR_NORMAL << endl;
cout << COLOR_BOLD_YELLOW_CYAN << "TEXT" << COLOR_NORMAL << endl;
