By looking at this question from both these aspects one comes to understand that both processes are needed. For instance there is the work of the color-merchant and that of the artist. The task of the color-merchant is to have different substances and to mix them and produce the desired color. The artist does not need to go through that process; he gets his colors ready-made from the color-merchant. In other words, it is not necessary for every person to pass through all the mineral, vegetable, and other aspects of creation, so there is no reason for distress!
