Principles of color matching and selection of watercolor colors

1. The color relationship on the color wheel

Before painting watercolor, we need to understand the color relationship of some watercolor colors. We use contrasting, complementary and analogous colors when we color. On the color wheel, two colors with a distance of 180° are contrasting colors, two colors within a 120° range are complementary colors, and two colors within a 60° range are the same color. In terms of color, it is divided into cool colors and warm colors. On the color board, warm colors are on the left and cool colors are on the right. The three primary colors are red, yellow and blue. These three colors can be matched with each other and mixed with other colors on the USB stick, but they are not colors that can be mixed.

2. The principle of warm and cold color matching

1. Warm color: Refers to the color that gives people a warm feeling.

The three main watercolor colors are red, yellow, and orange. Give people a positive, exciting, and warm feeling.

2. Cool color: refers to the color that gives people a sense of peace.

The three main watercolor colors are green, blue and purple. It gives a peaceful, cool, calm feeling.

3, the principle of matching with the color system

Same color system: The same color system means that there is a main color derived from various similar colors, and the main color and derived colors are combined in one picture. A color is often referred to as the same color. The same color system is often used in pictures with chaotic colors and different pictures, which can coordinate the pictures. When using the same color in different areas of the screen, pay attention to the shape of the color block. Another watercolor color relationship is the complementary color, which mainly plays a balancing role in watercolor painting and plays an important role in painting techniques. Complementary colors enhance the warm effect of the work and enrich the content of the picture, and are also more commonly used.
