By using black as the background color of the browser window, the image and video content you view will be much more visible to the human eye, with improved contrast and color rendering. Alternatively, a light or white background will cause your pupils to narrow, reducing your visibility and image clarity.

If you find it sub-optimal, please submit a trouble report so we can keep track of requests. We may offer the ability to choose your own background color. However, please note that we have received very favorable feedback about our background color choice.
