How to visualize a chessboard

WORK IN PROGRESS! NOT YET FINISHED! TO BE CONTINUED... 

In the Study Plan for Intermediate Players: Bringing it All Together! the wonderful Chess.com people recommend that intermediate players work on their visualization skills, and that we should be able to name the solor of each square on the board within 3 seconds. So, trying to this, I came up with a method I think works really well. And I would like to share it, hoping others might find it useful as well. 

The basic idea is this: it's easier to visualize a 4x4 board, than a regular, 8x8, chessboard. In fact, it's much easier. And using this little trick, we can learn the colors of every square on the board in very little time. 

To do so, let me first present to you the what I call the 4x4x4 chessboard. Here it is: 

Looking at the 4x4x4 board, you should see that it's essentially 4 4x4 boards, 2 black-and-white, and 2 black-and-grey. You will also notice that the letters a, b, c and d, as well as the numbers 1, 2, 3 and 4 are written in bold, unlike the remaining numbers and letters. The reason for this, is that this "miniature chess board" (the one containing the 16 squares from a1 to d4) is what we first have to learn. When we have done so, and this will be quick, we can use a little trick I discovered to "extrapolate" this 4x4 board to easily learn the colors of the entire board. 

So, we make things easier for ourselves, we begin with only this: 

Memorizing this is obviously easier than memorizing the entire board, but we'll start by simplifying matters even more, since I found this be speed up the process of learning to visualize the full chessboard.
