I'm trying to make text on a colored map more legible. Ideally I would add an outline around the text with the same general color as that part of the map, for a subtle blend. What's the best way to do this? Really hard cases are text boxes that span two different colors, and I'm prepared for manual work on those, but I'd like to find a faster way to quickly give text over a single-color area an outline that helps it blend with the background (I don't mind picking that color manually).
Thanks.
