A pigment contains one or more substantially spherical-shaped beads. Each substantially spherical-shaped bead includes one or more high aspect ratio particles encapsulated within an encapsulating material. Resinous compositions containing this pigment and a plastic, for example a polycarbonate, have a flowline-free colored, sparkling and/or metallescent appearance.
