The dependence of these criteria has been studied with the help of the integrated design model, developed in this study especially for coatings on exterior wood. The integrated design for the overall performance showed that the water-borne acrylic coating and the water-borne acrylic stain are the best choice as regards the environmental impact and durability of the coatings. The discussed surface coating systems were a solvent-borne alkyd coating, a water-borne acrylic coating, a water-borne crylic stain, a solvent-borne alkyd stain and alkyd oil.

Revisiting the weighting function for lightness in the CIEDE2000 colour-difference formula / Manuel Melgosa in COLORATION TECHNOLOGY, Vol. 133, N° 4 (08/2017)  

[article]  inCOLORATION TECHNOLOGY > Vol. 133, N° 4 (08/2017) . - p. 274-282 Titre : Revisiting the weighting function for lightness in the CIEDE2000 colour-difference formula Type de document : texte imprimé Auteurs : Manuel Melgosa, Auteur ; Guihua Cui, Auteur ; Claudio Oleari, Auteur ; Pedro J. Pardo, Auteur ; Min Huang, Auteur ; Changjun Li, Auteur ; Ming Ronnier Luo, Auteur Année de publication : 2017 Article en page(s) : p. 274-282 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Colorimétrie Fonction de pondération Index. décimale : 535.6 Couleur Résumé : We have used 13 experimental datasets (7420 colour pairs) to study the performance of the weighting function for lightness proposed by the CIEDE2000 colour-difference formula, because it has been suggested that this function can be improved by using the weighting function for lightness SL = 1 adopted by the CIE94 colour-difference formula. Using the standardised residual sum of squares (STRESS) index, it was found that: (i) replacing the SL in CIEDE2000 with SL = 1 improved the results for 7/13 datasets considered, but the improvement was statistically significant only for 1/13 datasets; (ii) a Whittle-type lightness-difference formula can be used to replace the term ?L*/SL in CIEDE2000, which led to a new colour-difference formula with no statistically significant difference with respect to CIEDE2000 for any of the 13 experimental datasets. A modification of the CIEDE2000 formula using a Whittle-type lightness formula is proposed.
