A tetris piece is a tetramino, which are 4 blocks connected into a figure. What you should do is spawn a figure, and make all of those blocks one color. You should use something like this.

We don't even know how you are creating your tetris. Are you using a library like sfml, sdl, opengel? So would be impossible for us to tell you how to change the color without making guesses.

@bads

I was able to compile your Tetris C++ program, using Dev-C++, but am unable to figure out exactly where you send the info to a function to draw the specified piece. If you can me know that location in the program, I should be able to color each shape a different for you.

Nice program you've made..
