The bright yellow color and the 'yello' logo.

A man in a white protective suit stands on a ladder, adjusting a light bulb. A woman stands nearby, looking at a laptop. The background is a bright yellow wall with sheer curtains. A yellow circle with the word 'yello' is in the top left corner. A large yellow square with text and a button is on the right side of the screen. The scene transitions to a black circle on a yellow background, then to the 'yello' logo on a yellow background, and finally to the 'yello' logo with text and a button.
