Structural color is often seen in nature because of its intense vibrancy and non-diminishing color. The ability to alter the color and optical characteristics through variations in geometric structure or material properties can lead to highly tunable or responsive coloration with applications such as displays and sensors. We describe the iridescent properties of complex emulsion droplets where the coloration is tunable via alterations in the droplet morphology, interfacial curvature, size, and orientation. We explore possible explanations for the optical mechanism and the dynamic characteristics of these fluid, structurally colored droplets.  <br/>
