WebThe NIR-reflectance properties of variously colored pigments ( e.g. white, yellow, and blue) are generally better than those of black pigments, because these pigments tend to reflect not only visible but also NIR light. 19,20 However, black pigments such as carbon black basically absorb NIR as well as visible light to store heat.

All subsequent samples were then measured relative to this established standard. Since the absolute reflectivity of the Spectralon® standard is known, the sample data was corrected to provide the absolute reflectivity of each sample.
