C++如何控制颜色（全面，最好是调色板级别的）？

如题，求助。

也搜过，大多只能调几种颜色。

最标准的是这个：

void color(int a) {
    if(a==0) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_GREEN|FOREGROUND_BLUE);
    if(a==1) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN|FOREGROUND_BLUE);
    if(a==2) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN);
    if(a==3) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE);
    if(a==4) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED);
    if(a==5) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_GREEN);
    if(a==6) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_BLUE);
    if(a==7) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED|FOREGROUND_GREEN|FOREGROUND_BLUE);
    if(a==8) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED);
    if(a==9) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY|BACKGROUND_GREEN|BACKGROUND_BLUE);
    if(a==10) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY|BACKGROUND_RED|BACKGROUND_BLUE);
    if(a==11) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED|FOREGROUND_BLUE);
    if(a==12) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED|FOREGROUND_GREEN);
    if(a==13) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY);
    if(a==14) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_GREEN|FOREGROUND_BLUE);
}

所以可不可以做一个调色板类型的，只要改变红绿蓝
参数就可以出颜色的那种？(⊙⊙)

控制台只能支持16色（4bit）或者256伪彩色（8bit）。你这个最好还是用windows gui图形编程
