This would be applied to all web pages viewed in the browser, not just for specific pages I am creating. I've looked at several plug-ins and applications that offer transparent browser windows, but nothing so far gives options for selecting colors to leave opaque. I essentially want something to act as a luma or chroma key for browser windows. I'm using OS X. This is for a project where text is overlayed on top of live video. The current version of the project relies on a video mixer. However I believe there should be a way to do this within OS X. <a href="https://secure.flickr.com/photos/mathunderwood/6965720266/in/set-72157629901415587">Example</a> tag:ask.metafilter.com,2012:site.213964 Fri, 27 Apr 2012 08:12:51 -0800 browser chromakey effects lumakey osx overlay transparency video web webbrowser davidriley
