Choose bg color?

Recently a couple of threads have shown the convenience of having a dark bg for certain photos. When evaluating my own photos in Photoshop I like to switch the bg to black and gray to see how it affects the contrast. I was wondering if a similar functionality could be implemented in the forum? Not that it´s gonna make a huge difference anyway, but it would be a neat feature I think.

Hi Ruben,

There is a difference between a black/dark/grey background, and a border to isolate an image from its surroundings (which is what we're actually after). The effect we're dealing with is also known as "simultaneous contrast", and there are interesting experiments to demonstrate the issue:

Some more food for thought:
