There is probably an obvious solution to this, but I haven't been able to figure this out by trying out or from tutorials etc. I'm using Photo & Graphic Designer.

So, if I need to change the colours of, say, a company's black logo to white when I have the logo only on jpg or equivalent, is it even possible? After removing the background basically only the outlines are left, so to my understanding this should be possible.

The main purpose is to show the customer how their logo would look placed in some item, for example, so no top quality outcome needed.

Much appreciated if someone can help a poor guy out!
