The large, floating number '500' and the bright yellow background.

The ad opens with a large, purple, 3D number '500' floating and blurring on a bright yellow background. A modern, light green smartphone stands vertically on the right side of the screen. As the ad progresses, the text 'Odmena' (Reward) appears next to the phone, with white arrows pointing towards it. The numbers '6x' and '500' are shown in purple, superimposed on the phone screen, with 'kč' (Czech Koruna) next to the 500. The ad concludes with the Raiffeisen Bank logo and website information.
