This seems like a simple issue and I found dozens of answers around this site and the web, but none of those has fixed my issue.
I'm trying to add a shape with rounded corners. I want the colors to be solid but they are blending with the background. I'm going to be making 100s of images, so I didn't want to have to copy & paste to a new layer and try and crop the off-color parts (like some of the solutions call for).
Any simple solution will be very much appreciated. If I have to use Illustrator I could, but I would prefer not to.
