I'm working on a project where I want to add a gradient over the bottom of a picture so it fades to the background. However, when I save the file to PDF, the gradient gets a grey color, not the black I selected. When I save as PNG, it doesn't change the color.
Should I change something in my settings somewhere? I've tried different PDF-viewers, but every viewer shows the same weird grey color.
Also, while we're at it, why does the gradient desaturate the image?
