I am looking for a way for all existing black arrows in my illustration to have a white halo to stand out against a colorful background in Illustrator. I would also like the halo to be easily changeable for all arrows (like when using graphic styles).
- Adding an additional stroke helps for ordinary lines, but does not outline the arrowhead.
- Copying an arrow, placing it in the back, slightly enlarging it and making white will surely work, but is tedious. Also, it cannot be saved as a graphic style, so cannot be automatically applied to the existing arrows (you will have to copy the one you created).
As you see, these theoretical solutions do not work. So, the question is is there a simple and automatic way to create halos for multiple existing arrows?
