BLUE COLORED COATED ARTICLE WITH LOW-E COATING
First Claim
1. A coated article including a multi-layer coating supported by a glass substrate, the coating comprising at least the following layers from the glass substrate outwardly:
- a first layer comprising silicon nitride;
a first contact layer comprising Ni and/or Cr;
an infrared (IR) reflecting layer comprising silver located over and directly contacting the first contact layer comprising Ni and/or Cr;
a second contact layer comprising Ni and/or Cr located over and directly contacting the IR reflecting layer;
a second layer comprising silicon nitride on the glass substrate located over at least the IR reflecting layer, the contact layers and the first layer comprising silicon nitride; and
wherein the first layer comprising silicon nitride is from about 72.5 to 110 nm thick, and wherein the coated article has the following glass side reflective color values;
a* from −
4 to +4, and b* from −
15 to −
25.

Abstract
A coated article is provided with at least one infrared (IR) reflecting layer, and is designed so as to realize good blue glass side reflective coloration in combination with desired solar control characteristics. In certain example embodiments, the coated is designed to realize rather negative glass side reflective b* values, in combination with fairly neutral glass side reflective a* color values and good sheet resistance and/or emissivity. The coated article may be used in the context of architectural or other types of window units in certain example embodiments of this invention.
