A visual value can be approximated by the help of the neutral gray chips of the Rock or Soil Color chart with ten intervals. The color parameters can be expressed with figures semi-quantitatively as: hue, value/chroma (H, V/C). The color "medium red" should serve as an example for presentation with the three color attributes, 5R 5.5/6.
Stucco used as an exterior coating on a residential building. Rock dash stucco used as an exterior coating on a house on Canada's west coast. The chips of quartz, stone, and colored glass measure approx. 3–6 mm (1/8–1/4"). The basic composition of stucco is lime, water, and sand. [4]
Whitewash was a mixture of lime and water which was brushed on the interior surfaces of partition walls; stucco was a longer-lasting, viscous blend of aggregate (in this case, sand) and whitewash, applied to the faces of load-bearing walls with a paleta . Usually the face of a wall that was to receive stucco would be scored so that the mixture ...
Color chips or color samples from a plastic pellet manufacturer that enables customers to evaluate the color range as molded objects to see final effects. A color chart or color reference card is a flat, physical object that has many different color samples present. They can be available as a single-page chart, or in the form of swatchbooks or ...
To protect the interior and exterior adobe walls, finishes such as mud plaster, whitewash or stucco can be applied. These protect the adobe wall from water damage, but need to be reapplied periodically. Alternatively, the walls can be finished with other nontraditional plasters that provide longer protection.
[citation needed] In historic Nasrid architecture, the composition and color of stucco varied depending upon the purity of gypsum stone and additives used to bestow properties to the mixtures such as hardness, setting time, and binding. [25]: 23, 56 The chemical formula for gypsum is CaSO 4 •2H 2 O. Gypsum is the most common sulfate mineral. [29]
Exterior insulation and finish system (EIFS) is a general class of non-load bearing building cladding systems that provides exterior walls with an insulated, water-resistant, finished surface in an integrated composite material system. EIFS has been in use since the 1960s in North America and was first used on masonry buildings.
PDF version of the chart. The colors of the chart were described by McCamy et al. with colorimetric measurements using the CIE 1931 2° standard observer and Illuminant C, and also in terms of the Munsell color system. Using measured reflectance spectra, it is possible to derive CIELAB coordinates for Illuminants D 65 and D 50 and coordinates ...
