Customizing image color in Illustrator
I downloaded a file with extension .al from the internet. When I was about to open it in Illustrator, it comes out with the Swatch Panel. The file has a monochrome background with the same shades of one color. It has thin curve grey lines in front of the background. Is there a way that I can separate the lines from the background then recolor it so it will not be visible with the eyes?
