Rapid and accurate determination of the formulation orientation of multi-layer capsule-shaped tablets with respect to different internal formulation layers proximate to the opposite narrow and rounded ends of the tablets is required. By including an appropriate color scheme in multi-layer osmotic tablets, detection of the formulation orientation is achieved by detecting the color at a spot location on a side of the tablet corresponding to one or another formulation layer or to one or another interface of two formulation layers depending on the formulation orientation of the tablet.
