1、Designation:D153514(Reapproved 2018)Standard Practice forSpecifying Color by the Munsell System1This standard is issued under the fixed designation D1535;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A num
2、ber in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This practice provides a means of specifying the colorsof
3、 objects in terms of the Munsell color order system,a systembased on the color-perception attributes hue,lightness,andchroma.The practice is limited to opaque objects,such aspainted surfaces viewed in daylight by an observer havingnormal color vision.This practice provides a simple visualmethod as a
4、n alternative to the more precise and more complexmethod based on spectrophotometry and the CIE system(seePractices E308 and E1164).Provision is made for conversionof CIE data to Munsell notation.1.2 This standard does not purport to address all of thesafety concerns,if any,associated with its use.I
