Chapter 3 of the book “Arts plastiques” is all about colors and how they can be used in art. In this chapter, we learn that colors are very important in making art look beautiful and interesting.

The chapter starts by explaining that there are three primary colors: red, blue, and yellow. These colors are special because they cannot be made by mixing other colors together. We also learn that when we mix two primary colors together, we get a secondary color. For example, when we mix red and blue, we get purple.

Next, the book teaches us about warm and cool colors. Warm colors, like red, orange, and yellow, make us feel happy and energetic. Cool colors, like blue, green, and purple, make us feel calm and relaxed.

The chapter also talks about how colors can create different moods in art. For example, using bright and bold colors can make a painting look exciting, while using soft and muted colors can make it look peaceful.

We also learn about complementary colors, which are colors that look really good together. For example, red and green are complementary colors. When we use them together in a painting, they make each other stand out.

Finally, the chapter ends by showing us some famous artworks that use different colors in interesting ways. It encourages us to experiment with colors in our own art and have fun creating beautiful and colorful masterpieces.

Overall, chapter 3 of “Arts plastiques” teaches us that colors are an important part of art and can help us express different emotions and create beautiful artwork.
