When you zoom out far enough so that the image becomes smaller than the window, the window background colour becomes visible. This defaults to grey, which is a good colour to ensure that your colour perception is accurate.
However, in earlier versions of PixInsight, I used to set this to black. I found this useful when setting the image background level - it then becomes easy to set the background level to be only just brighter than black (ideally no part of the image should become totally black). With a grey border around the image, it is much harder to judge this accurately.
Is it still possible to set the windows background colour? If so, how?
Thanks
