Beschreibung
Zusammenfassung:	A transparent or translucent coated article, comprising an optical substrate and one or more layers of anti-reflection material coated on at least a portion of the optical substrate, characterized in that said one or more layers having a thickness such that the article simultaneously has (i) a color, when viewed at a specified angle or angles, under a specified illumination, that is perceived to lie within a specified volume element of color space defined by the color's CIE chromaticity coordinates, and (ii) a perceived reflectance F=««S(»,¸)R(»,¸)d»d¸ that is less than or equal to 1.25F min , wherein » is wavelength, ¸ is incident angle, S(»,¸) is the human sensitivity function as a function of wavelength and incident angle, R(»,¸) is an average of p- and s-polarized reflectance, and F min is perceived reflectance minimized within the constraints imposed by said chromaticity coordinates.
