　　In the lecture, the professor talks about how artists use two elements to express meaning or emotions. The first is color. For example, the color red can express strong emotions and powerful statement, such as extreme joy or excitement, even anger. A calming color such as blue would give the viewer the feeling of ease and comfort. The other element is texture. When using rough texture, artists can evoke strong emotions and strength, while a smooth texture is less emotional. They can work together too. For example, a wide, rough brush stroke combined with red or orange creates the feeling of chaotic and wild. While a tiny, smooth brush stroke and soft color can express peaceful emotions.
