1. A glass article, comprising:
- (a) a glass substrate having a surface,(b) an iridescence-suppressing interlayer deposited on and adhering to the surface of the glass substrate;
(c) a first coating of a transparent thin film deposited on and adhering to said iridescence-suppressing interlayer; and
(d) a second coating of a transparent thin film deposited on and adhering to said first coating to form a coated glass article, said first coating having a refractive index of at least 0.2 greater than a refractive index of said second coating, said coated glass article having a single surface reflectance, Illuminant C at normal incidence from the film side, of one or less.

Abstract
A thin film stack applied onto a surface of a glass substrate. The thin film stack includes an iridescence-suppressing interlayer and an anti-reflective thin film stack applied over the iridescence-suppressing interlayer. The resulting coated glass article exhibits a low total reflectance and an aesthetically neutral color in reflectance from the film side.
