Field Testing of CIE DE2000 in Critical Areas of Color Space

摘要

The color difference formula recommended by AATCC, DECMC, is often reported to correlaternpoorly with expert visual assessment in certain regions of CIELAB color space, particularlyrnblues, grays, and dark colors. Recently, the CIE developed and adopted a new colorrndifference formula, CIE DE2000, in an attempt to overcome the deficiencies of currentlyrnrecommended color difference formulae such as DE94 and DECMC. The new formula has notrnyet been widely tested in an industrial color technology arena. In collaboration with ISO, thernAATCC research committee on color measurement, RA36, has commenced plant field trialsrnusing colored textile substrates to assess and compare the performance of DE2000 tornDECMC. Initial data are reported that compare these color difference formulae to visualrnassessment using color standards that lie in critical areas of color space.
