In the lower right corner of her poser scene window there are some coloured dots. One of them will change the background colour.  I usually have mine set to a grey tone, but for this example I changed it to blue.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
