Hi guys,

I'm very new to Inkscape and i don't have much experience with other design softwares.
I am wondering how to change the background color of an image. Is possible to do so? And if yes how?

Thank you so much

That depends on the image.
Can you post it ?

Two ways I can think of:
1) File -> Document properties -> Background color (mind also the transparency, by default the background is transparent)
2) Put an object (eg. a rectangle) of the desired color below all the rest (maybe on a layer apart that you put at the bottom).
