A coated article is provided with an absorbing layer(s). The coating is, in certain example embodiments, designed so that significant changes in visible transmission can be made by adjusting thickness of the absorbing layer without significantly affecting certain other characteristics such as certain color values. Such coated articles may be used monolithically or in the context of insulating glass (IG) units in different embodiments of this invention, and may or may not be heat treated.

1. A coated article including a coating supported by a glass substrate, the coating comprising: first and second infrared (IR) reflecting layers comprising silver, wherein said IR reflecting layers are spaced apart from one another by at least one dielectric layer that is located therebetween, and wherein the first IR reflecting layer is located closer to the substrate than is the second IR reflecting layer; anda metal absorption layer consisting essentially of NiCr located such that the IR reflecting layers are located over the absorption layer, wherein the absorption layer is sandwiched between and contacting first and second layers comprising silicon nitride. 2. The coated article of claim 1, wherein said first layer comprising silicon nitride is located between the glass substrate and the absorption layer and wherein a layer comprising zinc oxide is located between and contacting the second layer comprising silicon nitride and the first IR reflecting layer comprising silver. 3. The coated article of claim 1, wherein said first and second IR reflecting layers are spaced apart by at least: a layer comprising tin oxide, and a layer comprising zinc oxide. 4. The coated article of claim 1, wherein said coated article has a sheet resistance (Rs) of no greater than 5.0 ohms/square. 5. The coated article of claim 1, wherein said coated article has a sheet resistance (Rs) of no greater than 3.5 ohms/square. 6. The coated article of claim 1, wherein said coated article has a visible transmission of from 20-65%, measured monolithically. 7. The coated article of claim 1, wherein said coated article has a visible transmission of from 30-60%, measured monolithically. 8. The coated article of claim 1, wherein said coated article is an IG window unit having a visible transmission of from 15-60% and has an SHGC of no greater than 0.30. 9. The coated article of claim 1, wherein said coated article is designed so that when the thickness of only the absorption layer is changed to change visible transmission of the coated article by at least 7%, a glass side reflective a* value of the coated article does not change by more than 2.0. 10. The coated article of claim 1, wherein said coated article is designed so that when the thickness of only the absorption layer is changed to change visible transmission of the coated article by at least 10%, a glass side reflective a* value of the coated article does not change by more than 1.5. 11. The coated article of claim 1, wherein said coated article is designed so that when the thickness of only the absorption layer is changed to change visible transmission of the coated article by at least 15%, a glass side reflective a* value of the coated article does not change by more than 1.5. 12. The coated article of claim 1, wherein said coated article is designed so that when the thickness of only the absorption layer is changed to change visible transmission of the coated article by at least 15%, a glass side reflective a* value of the coated article does not change by more than 1.0. 13. The coated article of claim 1, wherein said coated article is designed so that when the thickness of only the absorption layer is changed to change visible transmission of the coated article by at least 10%, a glass side reflective b* value of the coated article does not change by more than 1.5. 14. A coated article including a coating supported by a glass substrate, the coating comprising: at least first and second infrared (IR) reflecting layers comprising silver, wherein said IR reflecting layers are spaced apart from one another by at least one dielectric layer that is located therebetween, and wherein the first IR reflecting layer is located closer to the substrate than is the second IR reflecting layer; anda metal absorption layer located such that the first and second IR reflecting layers are located over the absorption layer, wherein the absorption layer is sandwiched between and contacting first and second nitride inclusive layers. 15. The coated article of claim 14, wherein the coated article is heat treated. 16. The coated article of claim 14, wherein the metal absorption layer consisting essentially of NiCr is from 15 to 100 Å thick. 17. The coated article of claim 14, wherein the metal absorption layer is from 15 to 100 Å thick. 18. The coated article of claim 1, wherein the metal absorption layer consisting essentially of NiCr is about 33 or 63 Å thick. 19. The coated article of claim 14, wherein the metal absorption layer is about 33 or 63 Å thick. 20. The coated article of claim 14, wherein the absorption layer comprises Ni and Cr.
