The first paint should be uniform, not too thin or too thick, and the relationship between the two should be natural. Be careful not to show the final effect too early. If it has been drawn, it can be softened with a pen and then removed with a painting knife, so that the final shape will be more convenient.
It should also be noted that this layer of pigment is better to be more powdery and more prominent than the previous layer, that is to say, the contrast effect of color purity cannot be dragged out of the screen at one time, leaving a little room. It is best not to use color oil when painting this layer of color, which will have some unnecessary influence on the color contrast of the works. You can paint a small area with turpentine or a small amount of colored oil.
The teacher of Shanghai Studio specially reminded everyone that we should not miss any part, even some dark parts need to use this color layer as the background color. This is done to make the solid color of the work not sticky even if it is heavy, because the oil paint layer is very absorbent. Mastering oil painting knowledge can not only make you draw better, but also help you learn art more or less.
