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.

The coated article of claim 1, wherein one or both of the first and second contact layers comprises a nitride of NiCr and wherein the coated article is thermally tempered. 10. The coated article of claim 1, wherein the coating includes only a single Ag based layer which is the IR reflecting layer. 11. The coated article of claim 1, wherein the first layer comprising silicon nitride is in direct contact with the glass substrate. 12. The coated article of claim 1, wherein another dielectric layer is between the glass substrate and the first layer comprising silicon nitride. 13. The coated article of claim 1, wherein each of the first and second layers comprising silicon nitride further comprise aluminum. 14. The coated article of claim 1, wherein the coating consists essentially of the layers recited. 15. 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; an infrared (IR) reflecting layer comprising silver located over and directly contacting the first contact layer; a second contact layer located over and directly contacting the IR reflecting layer; a dielectric layer; 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. 16. The coated article of claim 15, wherein the first layer comprising silicon nitride is from about 75 to 105 nm thick, the dielectric layer comprises silicon nitride, and the coated article has the following glass side reflective color values: a* from-3 to +3, and b* from-16 to-23. 17. The coated article of claim 15, wherein the first layer comprising silicon nitride is from about 80 to 95 nm thick, and wherein the coated article has the following glass side reflective color values: a* from-2 to +2, and b* from-17 to-22. 18. The coated article of claim 15, wherein the coated article has a sheet resistance of no greater than about 10 ohms/square, a visible transmission of from about 30-60%, and wherein one or both of the contact layers comprises Ni and/or Cr. 19. The coated article of claim 15, wherein the coated article has a sheet resistance of no greater than about 10 ohms/square, and a visible transmission of from about 30-60%. 20. The coated article of claim 15, wherein the coated article is an insulating glass (IG) window unit. 21. 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; an infrared (IR) reflecting layer comprising silver located over and directly contacting the first contact layer; a second contact layer located over and directly contacting the IR reflecting layer; a dielectric layer; and wherein the coated article has a glass side reflective color value b* of from-15 to-25.
