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.
