RGB Specific Console Text Color C++

You need to use SetConsoleScreenBufferInfoEx to set this, see the ColorTable entry of the CONSOLE_SCREEN_BUFFER_INFOEX struct.

Console colors are a two-level process: there's the console attribute, which has four bits each for foreground and background (red, green, blue and intensity), which appears to limit the colors to the basic primary and secondary colors. But these values are used as indices to the color table, to determine the actual display value. So think of the character attribute 'color' bits as "logical red" etc rather than physical red. (The value that Character Attribute 'red' maps to is actually RGB red by default, but doesn't have to be.) So you're always limited to 16 indexed colors; but you can set those to whatever 16 full-RGB colors you want via the ColorTable.

The strip of colored squares you see in the dialog above is essentially that color table, and lists the colors in their Character Attribute order, the first suqare being 'logical black', and so on.

Sorry for being a little late to answer but here is the code you desire:

CONSOLE_SCREEN_BUFFER_INFOEX info;
info.cbSize = sizeof(CONSOLE_SCREEN_BUFFER_INFOEX);

HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
GetConsoleScreenBufferInfoEx(hConsole, &info);

info.ColorTable[0] = RGB(0,0,0);
...
info.ColorTable[3] = RGB(135, 206, 235);
...
info.ColorTable[15] = RGB (25,25,25);

SetConsoleScreenBufferInfoEx(hConsole, &info);

With this code you can change color values of all 16 index colors to any RGB color you desire.

Than you can print line with your desired color like this:

SetConsoleTextAttribute(hConsole, 3);
std::cout << "Hello World!" << std::endl;
