Product as the hero

We often need to put our product as the hero, particularly when we have a new product. We need to maximize the exposure of the product and feature it prominently, making it the focus of attention. We have two examples here for comparison. In the Oral-B one, the product is in blue and the background is blue too. Are we bringing the focus of attention to the toothbrush ? Understandably the brand colour of Oral-B is blue and there is nothing wrong to make the ad more blue dominant. But isn't that too much ?On the other, Puma chose to use a plain white background to highlight its new watch in black. You would see the difference between the two when they are put side-by-side.
