Could somebody please tell me how can I redefine the colour palette of the Console in C#?
Yeah, it's possible. You'll need a bunch of P/Invoke declarations to use code like this:
CONSOLE_SCREEN_BUFFER_INFOEX info;
info.cbSize = sizeof(info);
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
GetConsoleScreenBufferInfoEx(hConsole, &info);
info.ColorTable[14] = RGB(255, 128, 0); // Replace yellow
SetConsoleScreenBufferInfoEx(hConsole, &info);
SetConsoleTextAttribute(hConsole, FOREGROUNDINTENSITY | FOREGROUND_RED | FOREGROUND_GREEN);
Visit pinvoke.net or use the P/Invoke Interop Assistant to get the declarations you need to use this code.
