Scope: This document establishes the general principles of urban color design, provides the factors to be considered, design content and results of urban color design, and serves as a guide for urban color-related work. This document is applicable to color design and management in urban and rural construction in the entire spatial domain, and is also applicable to the teaching and scientific research of urban color design.

Introduction

National Standard of the People's Republic of China GB/T 42648—2023_Guidelines for Urban Color Design

1. Background of Standard Formulation and Analysis of Technical Evolution

With the acceleration of urbanization and the improvement of people's requirements for the quality of living environment, urban color design has gradually become an important means to enhance the image of the city and the quality of life of residents. GB/T 42648—2023 "Guidelines for Urban Color Design" is a standard formulated on the basis of extensive research and practical experience, aiming to provide scientific technical guidance for urban planning, construction and management. This standard combines the research results of multiple disciplines such as architecture, color science, and psychology, and reflects the evolution process from theory to practice.

Dimensions	Key elements	Key points of design
Natural conditions	Sunshine, soil, vegetation, etc.	According to different types of sunshine (low, medium, high), adjust the brightness and saturation of architectural colors; consider the colors of regional soil and vegetation to form a harmonious urban color.
Historical culture	Traditional architecture, handicrafts, etc.	Extract color inspiration from local traditional culture and reasonably use modern design techniques.
Times of development	New materials, new technology	Combined with scientific and technological progress, innovative urban color design solutions, enhance the sense of technology and modernity of design.

2. Comparative analysis of standard frameworks

Division of design content levels

Urban color design is divided into three levels: macro, meso and micro.

Macro level: Involving the overall planning of national land space, focusing on the overall positioning and vision of urban color. Through cross-regional collaboration, constructing landscape patterns and showing regional characteristics.
Meso level: Implemented in the detailed planning stage, refine the design requirements of key areas, linear spaces, etc., and emphasize the spatial layout and order of colors.
Micro level: Take the plot as the smallest unit, conduct refined design, consider the difference between material color and effect color, and ensure the practical operability of the design plan.

3. Implementation suggestions

3.1 Macro design implementation suggestions

At the macro level, it is recommended to focus on:

Clarify the city color theme in combination with the city's positioning.
When zoning, consider factors such as natural boundaries and functional zoning to avoid simply determining the color according to the orientation.
Establish a complete color control system to ensure the continuity and consistency of the design.

3.2 Meso design implementation suggestions

At the meso level, it is recommended to focus on:

Clearly divide the color requirements for key areas and general areas.
In linear space design, pay attention to the coordination of visual effects of distant, medium and near views.
Establish a list of colors that should not be used to avoid visual conflicts.

3.3 Micro-design implementation suggestions

At the micro level, it is recommended to focus on:

Measure environmental effects to ensure a reasonable match between material color and effect color.
Use plots as units and develop detailed color spectra and maps.
Make control tools (such as color cards and color scales) to facilitate practical operations.
