I have a graph exported in an EPS format from Matlab, and I wanted to change some of the symbol colours. Is there any way to do this without having to hold down the shift key when accessing the shape fill/line colour option? I guess the symbols are not vector files which is why I can’t change the colours more easily.
1) From the Swatches panel, click the flyout menu and select Add Used Colors. This will create and apply a global swatch for every color Illustrator finds in the art.
2) Edit your desired color swatches as necessary. Editing a global swatch will be reflected in all object that have been assigned to that swatch.
