In Illustrator, you can change the color of any object by converting it into a tracing object and then into a path using the “Image Trace” tool and the “Expand” tool. After that, you can continue by filling up the path with another color using the “Fill” option.
To do this, first, go to the “Window” tab at the top menu and make sure to select the “Control” option.
Once done, go to the Image settings at the top, click on the downward arrow beside “Image Trace” and select “16 colors”.
From there, click on the “Expand” button that will appear, still at the top menu.
The next step is to click on the “Direct Selection Tool” from the toolbar on the left. This will let you see the paths in your image.
Now you can select the part of your image that you want to change the color of. From there, go to the “Appearance” window at the “Properties” tab and select the “Fill” option. There you can select the color of your choice.
And there it is! You can now change the color of your image in Illustrator.
