Top Lamp: This is Goldie’s Temperature Lamp, which helps you understand how your starter is feeling. The Temperature Lamp is always on, and displays one of three colors.
Blue when your starter is feeling chilly and sluggish in your cool kitchen.
Gold when your starter is just right, tucked into the Goldilocks Zone, healthy and active.
Red when your kitchen has gotten too hot, overheating and exhausting your starter.
Most baker's kitchens are in the blue all year round. Goldie's job is to keep your starter out of the blue zone whenever you want an active starter.
Live with these three temperature lights for a bit and you will start seeing the world through the eyes of your starter. Your starter will become less mysterious and more dependable.
Bottom Lamp: This is Goldie’s  Auto-Warming Lamp, which indicates that the auto-warming feature has been activated. If the bottom light is off, it means auto-warming is turned off.
