A coated substrate is covered with a barrier or base coating having spaced apart transparent electrodes deposited thereon. The base coating and electrodes are arranged such that the electrodes and the base coating together and the base coating alone have at least matching photopic reflectivity in a selected liquid, and preferably have matching spectral response in the selected liquid, over a wavelength range between about 470 and 650 nm.

[ What is claimed is:] [1.] A coated substrate, comprising:a base coating deposited on the substrate, and a plurality of spaced-apart transparent electrodes formed on the base coating and exposing the base coating therebetween, the electrodes and the exposed base coating therebetween configured to be immersed in a selected liquid;each of the electrodes including at least three layers, each of said three layers having an extinction coefficient less than 0.10 at about 520 nanometers, any adjacent two of said three layers having a different refractive index, and said three layers designated as first second and third layers in consecutive numerical order;said third layer being adjacent said base coating and being a layer of a transparent electrically conductive material having a refractive index between about 1.8 and 2.2 at a wavelength of about 520 nanometers;said base coating including at least one layer of a dielectric material, said at least one layer being adjacent said third layer; andsaid base coating alone having a first spectral response in the selected liquid, and the base coating and any electrode together having a second spectral response in the selected liquid, said first and second spectral responses in the selected liquid substantially matching in a wavelength range between about 470 and 650 nanometers.
