Abstract The presented datasets concerning the colour choices documented in the 1713 inventory within the two apartments of William III of Orange-Nassau (1652-1702) at Het Loo palace (Apeldoorn) for historical mapping correspond to the article: Bernert, Sara. 'Interior Colour Practices in the Apartments of William III of Orange-Nassau at Het Loo Palace. A New Methodology for Digital Reconstruction through the Use of GIS'. In New Digital Approaches, edited by Krista De Jonge and Sanne Maekelberg, 71–88. PALATIUM, 2023. This methodology deals with the captivating world of interior colour practices in stately apartments within courtly contexts, using the power of digital humanities. The aim is to bridge historical sources, such as palace inventories, with their corresponding spaces with a Geographic Information System (GIS). Please see the PDF for further description. Dataset Contents The separate CSV sheets and the equivalent Excel workbook[2] include: The datasets of colour carriers, their quantities and described colours by room as noted in the inventory: Overall colour distribution across both apartments: In short form for the macro layer of the palace for an over-regional comparison.[3] And a detailed version of the microlayer of the palace.[4] A separate dataset of the first apartment of William III as it was around 1686, still in his function as Prince of Orange and Stadtholder of Holland, Zeeland, Utrecht, Guelders, and Overijssel.[5] A separate dataset of the second apartment of William III in the state around 1694, as he had already become King of England.[6] Precise data on the polygons of the ground plan from 1695.[7] Furthermore, the key to colour factoring by the space the colour carriers take up within the room, as described in the associated article pp.73-74.[8] _______________________________________________________________________________ [1] The inventory was amongst other inventories of the Orange-Nassau dynasty published in the 1970s and is accessible online: Sophie Wilhelmina Albertine Drossaers and Theodoor Herman Lunsingh Scheurleer, eds., ‘Inventaris van de Inboedel van Het Huis Het Loo, Het Oude Loo En Het Huis Merwel 1713’, in Inventarissen van de Inboedels in de Verblijven van de Oranjes En Daarmee Gelijk Te Stellen Stukken 1567-1795, vol. 1, 3 vols, Rijks Geschiedkundige Publicatiën, GS 147 (Den Haag: Rijks Geschiedkundige Publicatiën, 1974), 647–94, https://resources.huygens....
