Answer 1

On windows you can use SetConsoleTextAttribute from the windows header.
https://docs.microsoft.com/en-us/windows/console/setconsoletextattribute

And the attributes:
https://docs.microsoft.com/en-us/windows/console/console-screen-buffers#span-idwin32characterattributesspanspan-idwin32characterattributesspancharacter-attributes

So for example to do what you asked you would do something like this:

#include <iostream>
#include <windows.h>

// c = 7 for default color
void setConsoleColor(WORD c)
{
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), c);
}

int main()
{
setConsoleColor(FOREGROUND_RED | BACKGROUND_BLUE | BACKGROUND_GREEN | BACKGROUND_RED );
std::cout << "Hello\n";
setConsoleColor( BACKGROUND_BLUE | BACKGROUND_GREEN | BACKGROUND_RED );
std::cout << "Goodbye\n";
setConsoleColor(7);
}

Use the | operator to combine attributes.

And just like Manual said, this doesn't work on SL.

Answer 2

You need to find what c++ code is used to change color for your os.

search c++ change text color for what you run code on.

- does not work on SL.
