I would basically ignore any textbooks or "tutorials" and just start with drawing first, which has the advantage that you can ignore colors. When I was 19, I learned how to draw over the course of 3 years, by using standard printer paper, a pencil and photographs to copy. It was incredibly frustrating during the first few days, but you will get better very quickly. After a few weeks, you will realize that your perception of an image (and your idea of drawing) will change completely. You will see an image in 3 dimensions, and you will quickly learn how you can add "depth" to an image. It's difficult to describe, but basically it will suddenly feel like your pencil is "diving into" the picture you are drawing, as opposed to just scratching on the paper surface. Something I did not expect was that the other major thing you learn during the first few weeks is not how to draw, but how to fix mistakes you made. This was an important realization for me, because it extends to many other professions as well. After you have copied a few images, you will realize the shortcomings of your tools (paper, pencil, eraser) and you will start to look for other pencil types or better quality paper. All of this will come naturally after a while, you don't need textbooks for that, and you can apply this type of learning to many other skills afterwards, because you will have developed an immunity against these frustrating, frustrating first days.
