In the Roman wall paintings different white colours were used, named Paraetonium, Melinum, Anularia, Eretria, Argentaria, etc. FTIR, Raman spectroscopy and X-Ray diffraction were applied to study different white pigments, such as calcite, aragonite, dolomite and huntite, white carbonates present in archaeological findings from Roman walls in the Mediterranean region. This study showed that it is possible to distinguish and identify these components in white colours. About 450 samples of Roman wall paintings were analysed and it was observed that often aragonite is associated to precious coloured pigments. On the basis of the obtained results some considerations about the period in which the different kinds of white pigments were used are proposed.
在罗马壁画中使用了不同的白色颜料，如帕拉埃托尼亚白、梅利努姆白、阿努拉里亚白、埃雷特里亚白、银白等。傅里叶变换红外光谱（FTIR）、拉曼光谱和X射线衍射被用于研究不同的白色颜料，如方解石、文石、白云石和白钙镁矿，这些白色碳酸盐存在于地中海地区罗马城墙考古发现中。这项研究表明，可以区分和识别白色颜料中的这些成分。分析了约450个罗马壁画样本，观察到文石通常与珍贵的彩色颜料有关。基于所得结果，对不同种类白色颜料的使用时期提出了一些看法。
