Enhancing Preservation of Ancient Buildings through Color Imagery Analysis and Activation: Take Yuelu Academy as an Example

Abstract The pivotal role of color imagery analysis and activation has been insufficiently explored in the realm of historic heritage conservation. This study addresses this issue by introducing a comprehensive methodological framework that encompasses acquisition, analysis, activation, and application of color information based on the NCD color system, an innovative color semantic quantification theory. Utilizing the venerable Yuelu Academy (from A.D. 976) as a case study, color imagery analysis methods across diverse spatial scales have been summarised. Subsequently, these results are applied to activate the surrounding environment color, as well as its cultural souvenirs. The methodologies outlined herein hold profound significance in addressing challenges concerning visual color continuity in the preservation of historic architectural landscapes, offering innovative perspectives.
