Serato Scratch Live : Swayzak Mode

I was playing at the first Sunday Session this year and the Sun was so bright that I couldn't read the Serato screen. Matty Matt came over to me and pressed some buttons on my computer and I was suprised to see my backdrop change color. It turned everything purple, pink, and black. I went on playing and everything was cool. What I found out later was that the screen was set to "negative" mode. I played every gig since with this new backdrop. I can't even look at Serato anymore in the regular mode.
