A coated article is provided so as to have fairly neutral a* and/or b* color values at high viewing angles such as 45 and/or 60 degrees off-axis. In certain example embodiments, the neutral a* and/or b* values at high viewing angles (VA) are caused by lessening the thickness of a bottom titanium oxide layer. Coated articles herein may be used in the context of insulating glass (IG) window units, or in other suitable applications. The coating comprises at least, outwardly form the glass substrate: a layer comprising titanium oxide, a dielectric layer, a contact layer, a fist layer comprising silver provided over and in contact with said contact layer, a dielectric layer, a second layer comprising silver, a dielectric layer.
L'invention concerne un article revêtu prévu pour présenter des valeurs de couleur a* et/ou b* relativement neutres à de grands angles de visualisation tels que des angles de 45 et/ou 60 degrés hors axe. Dans certains exemples, les valeurs neutres a* et/ou b* à de grands angles de visualisation peuvent être réduites par amincissement d'une couche d'oxyde de titane inférieure. Lesdits articles revêtus peuvent être utilisés dans le contexte d'unités de fenêtre à vitrage isolant (IG) ou dans d'autres applications appropriées.
