The bright yellow background and the "yello" logo.

The ad opens with a man in a purple sweatshirt against a bright yellow background. A yellow circle with the word "yello" is in the top left corner. The man looks around and gestures. A clapperboard appears briefly. The man then smiles and points to a yellow text box that appears on screen. The text box contains marketing copy and a button. A starburst graphic with "Aus 79% Ökostrom" appears. The graphic changes to "Aus 100% Ökostrom". The man continues to smile and gesture. The ad ends with the "yello" logo and the tagline "Gute Energie."
