Decorative paintings have been widely used around the world, not only in modern times but also dating back thousands of years when they were used to decorate interiors. Over time, decorative paintings have evolved in many different ways. Their expression has become more stylized, emphasizing rhythm, order, and dynamic movement. The process of creating a decorative painting, from production to final product, follows a certain order, with the paintings and spaces interacting with each other, leading to the creation of something truly special. This mutual influence drives the development of decorative art, embedding it in our minds and gradually shaping a cultural aesthetic that reflects national characteristics.

1. The Relationship Between Decorative Paintings and Space Function and Lighting

1.1 The Relationship Between Decorative Paintings and Interior Space Function

The arrangement of interior spaces needs to be designed according to the occupants’ living habits, with interior decorations fulfilling specific roles. For instance, in the bedroom, decorative paintings with peaceful shapes and colors, either soft and elegant or warm and flowing, can enhance sleep and emotional communication. In public spaces, such as crowded leisure areas, abstract decorative paintings help emphasize modern rhythm and harmony. Therefore, when choosing decorative paintings for entertainment venues, colors should be contrasting, and abstract patterns should feature strong dynamic elements. The selection of decorative paintings should match the function of the space to best highlight its value.

1.2 The Relationship Between Decorative Paintings and Interior Lighting

Indoor lighting and decorative paintings complement each other in both visual and spatial dimensions. Lighting affects the atmosphere created by decorative paintings, with different types of lighting producing varied effects. For example, black and white lighting can evoke positive or negative emotions, while bright lighting enhances the vibrancy of colors, inducing feelings of excitement and joy. Conversely, dim lighting can make paintings appear gloomy and depressing. Since lighting brightness, warmth, intensity, and direction are determined by the designer, there is a direct relationship between indoor decorative paintings and lighting.

1.3 The Influence of Decorative Paintings on Interior Space Shape and Color Scheme

Typically, the placement of decorative paintings in interior spaces should align with the overall spatial structure. In larger spaces, larger decorative paintings are generally used, while smaller spaces require adjustments to the proportions of the paintings. The shape of the paintings may vary depending on the space, and should not always be conventional. The diversity of modern architecture has led to more personalized and expressive interior spaces, so the selection of decorative paintings should match the interior environment, enhancing the overall atmosphere. Paintings are usually placed on walls or ceilings, and their colors and artistic treatment should be tailored to the specific space.

2. Principles of Using Decorative Paintings in Interior Spaces

This section analyzes the use of decorative paintings in key areas such as bedrooms, living rooms, dining rooms, and bathrooms, following three different principles.

2.1 The Principle of Color Harmony Between Decorative Paintings and Interior Spaces

The harmony of colors in interior decoration and their relationship with the spatial environment is crucial. The colors of decorative paintings and their surroundings should be coordinated to create a unified overall look. The use of color in decorative paintings is guided by principles such as brightness, purity, and hue. For example, in the bedroom, low-contrast harmonious colors with soft hues are often used, with abstract or landscape paintings being preferred. In dining rooms, simple and elegant environments can be enhanced by European-style wall decorations, with the emphasis on simplicity and brightness in the colors of the paintings. The living room, being a key decorative space, should use decorative paintings to complement the overall style and enhance its aesthetic appeal.

2.2 The Emotional Impact of Color in Decorative Paintings

Different colors evoke different visual and emotional responses. As an important form of interior decoration, decorative paintings must consider the visual and emotional impact of colors. For example, a red wall painting in a bedroom can create a romantic, passionate atmosphere, while children’s bedrooms often use high-purity light blue, light pink, or warm green colors, with matching decorative paintings. For older adults, traditional and sophisticated colors with higher saturation are preferred, and in bathrooms, white or blue paintings create a clean and serene atmosphere, complementing the space’s function.

2.3 The Need for Spatial Composition

The composition of decorative paintings should align with the spatial form of the environment. For instance, in a rounded interior space, square or angular decorative paintings can break the balance, creating a new spatial effect. In corner areas, such as stairways, square or circular wall paintings can create a visual dislocation effect. In spaces with cubic or rectangular frames, decorative paintings can extend the space, creating a sense of depth. Decorative paintings, due to their varied spatial compositions, can also alter the function of interior spaces, striving for harmony and unity while reinforcing the use of space.
