This is probably super simple. I do a lot of transparency stuff for the Web. My background color for the most part turns out to be black. I get my transparency but the program I'm using at the moment does a cleaner job with white. When it's black I see a little trash of black around the edge of the graphic. In the past I've come up with white quite by accident and it was clean as a whistle. I'm exporting as PNG, True Color + Alpha. I know I'm missing something, but don't know what. Any input at all appreciated.
