Townscape Colour Development with the IroKage Intelligent Colour Planning Support System

摘要

Aesthetics of townscapes have been a main factor in urban development. The present authors have introduced IroKage, an intelligent colour planning support system for improving townscapes. The system offers colour combination proposals based on three elements: colour harmony, impressions of the townscape, and cost for the change of colours. The system is constructed using an evolutionary algorithm and the Kansei engineering approach. In this paper, townscape colour development is conducted using IroKage. The goal of the development is to realize the townscape colours fitting for the impressions of historical districts in Kyoto. The development demonstrates that the system achieves sufficient ability to propose appropriate colour combinations with minimum colour changes
