Just started using your theme. I’ve tried to adapt the portfolio slider Santa icon as a full-screen slideshow for my splash page. Looks great except most of the slides have a colored background, but some don’t. I’ve looked thru the settings for each slide and it seems they are identical. Is there a layer under the slide image that I’m not aware of? Here’s a URL: http://www.wordpix.ca/muse/wordpress/
If you want to make those slider to have fullscreen width you can enable the Force Full Width option on the Slider Settings to achieve that. Actually there is no additional layer under the slide image, but there is a background color for the slider. You can try to change the background color on the slider settings.
