This practice provides a means for specifying the colors of objects in terms of the Colorcurve system. Both computational and visual methods are included. This practice is applicable to inked, painted, dyed, or mass-colored surfaces viewed by an observer with normal color vision.

Formerly under the jurisdiction of Committee E12 on Color and Appearance this practice was withdrawn in June 2007.

This standard is being withdrawn without replacement because the materials for this system are no longer available.

1.1 This practice provides a means for specifying the colors of objects in terms of the Colorcurve system. Both computational and visual methods are included. This practice is applicable to inked, painted, dyed, or mass-colored surfaces viewed by an observer with normal color vision.

1.2 This practice includes a method for producing a color specimen to match a Colorcurve sample.

1.3 This practice does not cover the preparation of specimens. If specimen preparation is required in conjunction with this practice, a mutually agreed upon procedure shall be established.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
