(1) Background: This paper illustrates an innovative methodological approach chosen to study and map the colors of the medieval wall painting of Santa Maria Antiqua in the Roman Forum, one of the pilot sites of the EHEM project (Enhancement of Heritage Experiences: The Middle Ages). Digital Layered Models of Architecture and Mural Paintings over Time). (2) Methods: Two methods were employed to gather information about colors and mapping. Specifically, colorimetry was utilized for spot measurements, and hypercolorimetric multispectral imaging (HMI) was employed to map the same colors sampled through colorimetry. (3) Results: Chromatic data for all colors in the wall paintings were obtained in the CIELAB color space. Additionally, chromatic similarity maps were generated using the innovative HMI system, a multispectral imaging technique capable of obtaining color data information through advanced calibration software named SpectraPick (Version 1.1). This comprehensive approach facilitates a thorough understanding of color characteristics and distribution. (4) Conclusions: The color measurements and mapping represent significant advancements in the interpretation of medieval wall paintings, which are often fragmentary and stratigraphically complex. This research sheds new light on the colors used and enhances our understanding of the original appearance of the iconographic patterns. Furthermore, it enables the reconstruction of colors that closely resemble the originals.
(1) 背景：本文阐述了一种创新的方法，用于研究和绘制罗马广场上圣玛丽亚古教堂中世纪壁画的颜色，该教堂是EHEM项目（遗产体验提升：中世纪）的试点地点之一。随着时间推移的建筑和壁画数字分层模型。(2) 方法：采用两种方法收集有关颜色和绘图的信息。具体而言，比色法用于定点测量，超比色多光谱成像（HMI）用于绘制通过比色法采样的相同颜色。(3) 结果：在CIELAB颜色空间中获得了壁画中所有颜色的色度数据。此外，使用创新的HMI系统生成了色度相似性图，这是一种多光谱成像技术，能够通过名为SpectraPick（版本1.1）的先进校准软件获取颜色数据信息。这种综合方法有助于全面了解颜色特征和分布。(4) 结论：颜色测量和绘图代表了中世纪壁画解读方面的重大进展，这些壁画往往支离破碎且地层复杂。这项研究为所使用的颜色提供了新的见解，增强了我们对图像图案原始外观的理解。此外，它还能够重建与原作非常相似的颜色。
