Article including a non-light-emitting variable transmission device and a coating

An article comprising:

• a non-light-emitting, variable transmission device on a substrate;
• a coating disposed between the non-light-emitting, variable transmission device and an ambient outside the article, wherein the coating comprises a plurality of layers including a first layer having a refractive index of at least 2.2 and a thickness of between 17 nm and 40 nm wherein the coating comprises silicon-zirconium oxynitride;
• and
• wherein the article has a color difference delta E(ΔE) in the range of 1.0 to 6.5, wherein:
• ΔE=(L*212+a*212+b*212)0.5,
• L*21 is the difference in L* when the article is in its lowest transmission state minus L* when the article is in its highest transmission state,
• a*21 is the difference in a* when the article is in its lowest transmission state minus a* when the article is in its highest transmission state,
• b*21 is the difference in b* when the article is in its lowest transmission state minus b* when the article is in its highest transmission state,
• measurements for L*, a*, and b* are taken along the same side of the article as the outer surface, wherein L* represents the lightness of color, a* represents a position between red/magenta and green, and b* represents a position between yellow and blue according to CIELab color space, wherein when the article is in its highest transmission state, the article comprises a luminous transmission in a range of 40% to 60%.
