I have a stock image I downloaded from adobe stock: Minimal Nashville Linear City Skyline with Typographic Design - Buy this stock vector and explore si...
I want to make something like this: Atlanta Skyline Invitation
The issue I am facing is, how do I make the skyline itself not transparent? If I put a black background on it then it all goes black because there is no fill to the skyline but when I open it in illustrator there isn't a way to change the fill for the individual buildings.
Please let me know if this is possible. Thank you!
What editing tool do you use? Illustrator? Photoshop?
As mentioned by Abambo, it depends on which application you are using to do that. Did you check if that part of the art is locked (Layers panel)? If not, please do. That could be the reason you are not able to add a Fill.
