Abstract:
Devices and methods for measuring color of a target coating are provided. In an exemplary embodiment, a color measurement device includes a housing configured for placement on a target coating. A source connected to the housing directs a beam of electromagnetic radiation towards the target coating at an entrance angle. A spherical coordinate system is used, where the entrance angle is a polar angle measured from a zenith that is normal to the target coating surface. First and second detectors are connected to the housing at a first and second polar angle, respectively, to measure the electromagnetic radiation reflected by a target population of flakes within the target coating, where all the flakes in the target population of flakes have the same angled flake normal polar angle. The first polar angle is different than the second polar angle.
