敦煌莫高窟第45 窟《观无量寿经变》壁画不仅是盛唐时期佛教艺术的巅峰之作，更是一座蕴含深邃象征逻辑的色 彩美学宝库。其色彩体系超越了单纯的装饰功能，成为构建神圣空间、推进叙事节奏、传达宗教哲学的核心视觉语言。然而， 实体洞窟的保护限制与颜料老化，使得这一色彩体系的全面认知与深度体验面临挑战。研究以第45 窟《观无量寿经变》为对象， 聚焦于其色彩体系的数字化转译与沉浸式再现。首先，系统解构壁画色彩的物质构成、象征体系及其在“未生怨”与“十六 观”叙事中的时空定位。其次，探讨基于虚拟现实（VR）技术进行高保真色彩采集、材质重建与动态渲染的技术路径。进而， 创新性地提出色彩叙事交互框架，将色彩变化作为驱动用户沉浸体验、理解观想次第、实现情感共鸣的关键交互媒介。

The mural in Cave 45 of the Mogao Caves, "The Transformation of the Sutra of Perfect Nirmāna", is not only the pinnacle of Buddhist art during the Tang Dynasty, but also a treasure trove of color aesthetics with profound symbolic logic. Its color system transcends the simple decorative function and constitutes the core visual language for constructing a sacred space, advancing the narrative rhythm, and conveying religious philosophy. However, the protection limitations of the physical cave and the aging of the pigments pose challenges to the complete understanding and in-depth experience of this color system. The research focuses on the digital translation and immersive reproduction of the color system of the "Transformation of the Sutra of Perfect Nirmāna" in Cave 45. Firstly, it systematically dissects the material composition, symbolic system of the mural colors, and their roles in space and time within the narrative of Unborn Anger and Sixteen Views. Secondly, it explores the technical path of high-fidelity color acquisition, material reconstruction, and dynamic rendering based on virtual reality (VR) technology. Finally, it innovatively proposes the Color Narrative Interaction framework, using color changes as a key interactive medium to drive the user's immersive experience, understand the sequence of contemplation, and achieve emotional resonance.
