Yes. Glass for Europe (formerly GEPVP) have issued a Code of Practice that describes a method for allowing an objective evaluation of the colour of coated glass, as defined in EN 1096-1, when used in facades.

It provides a method for measuring colour differences within the same glass pane and between two adjacent panes in the same façade. Specific requirements are given for coated glass, dependent upon its light transmittance and reflectance. Guidance is also provided on angle dependency, reflection from the interior and transmission.
