Abstract
Provided is a cooking appliance that includes an oven cavity and an oven door is pivotally coupled adjacent to an entrance leading into the oven cavity, and a method of controlling such a cooking appliance. The oven door includes a substantially opaque region that interferes with external observation of the oven cavity while the door is in the closed orientation, and an electrochromic indicator provided to the opaque region. The electrochromic indicator includes a material with a first appearance that renders the electrochromic indicator substantially indistinguishable from the opaque region in a first operational state, and a second appearance in a second operational state that contrasts with the opaque region to issue a notification related to operation of the cooking appliance.
