  2. Paint sheen - Wikipedia

    en.wikipedia.org/wiki/Paint_sheen

    The sheen [4] or gloss level of a paint is principally determined by the ratio of resinous, adhesive binder, which solidifies after drying, and solid, powdery pigment.The more binder the coating contains, the more regular reflection will be made from its smooth surface; conversely, with less binder, grains of pigment become exposed to the surface, scattering the light and providing matte ...

  3. Color chart - Wikipedia

    en.wikipedia.org/wiki/Color_chart

    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 ...

  4. Light reflectance value - Wikipedia

    en.wikipedia.org/wiki/Light_Reflectance_Value

    LRV on Paint Swatch. In architecture, light reflectance value (LRV), is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. [1] The measurement is most commonly used by design professionals, such as architectural color consultants, architects, environmental graphic designers and interior ...

  5. Drawdown card - Wikipedia

    en.wikipedia.org/wiki/Drawdown_card

    Drawdown cards are used for testing paints and coatings through wet film preparation.. Black and white cards are used to measure both opacity and contrast ratio.By measuring reflectance values of both parts of the card one can gain a quantitative opacity value of a paint sample.

    en.wikipedia.org/wiki/Federal_Standard_595

    Federal Standard 595 is the color description and communication system developed in 1956 by the United States government. Its origins reach back to World War II when a problem of providing exact color specifications to military equipment subcontractors in different parts of the world became a matter of urgency.

  7. Drawdown chart - Wikipedia

    en.wikipedia.org/wiki/Drawdown_chart

    Initially the desired coating is applied in a puddle on the drawdown chart. Then the bar is placed at the top of the chart, and drawn down over the paint in order to spread it evenly along the length of the chart. Once this evenly spread paint dries, it can be tested for a variety of properties. [5]

    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 ...

    At the international furnishing fair imm Cologne, 13-19 January 2020, two new colours were presented in the Classic Collection: RAL 2017 RAL orange and RAL 9012 Cleanroom White. [4] "RAL 840-HR" covered only matte paint, so the 1980s saw the invention of "RAL 841-GL" for glossy surfaces, limited to 193 colours. [5]
