Abstract: A test apparatus comprising a portable reference element having color and spectrophotometrically neutral gray elements of predetermined hues and saturations, and a digital software file provides identical color and spectrophotometrically neutral grayscale data which, when printed or otherwise reproduced accurately, may be compared with the test colors and grayscale provided by the portable reference element, enabling appropriate adjustments to be made to the printer as required.

Abstract: Embodiments described herein disclose a color measurement device and method for use with cameras or other imaging devices. The color measurement device may be configured to determine many different colors via a commonly owned device. Embodiments utilize sinusoidal grayscale rings to determine an exact color match of an unknown color, even if there is perspective distortion of an obtained image.
