I finally used Del Sol - Holly Berry. It's fabulous!! It works so well and both colors are really gorgeous. The purple isn't a true purple like the label, it's more of a red-tinged purple, but still amazing. I need to find a polish that color, because I'm in love.
I didn't take a video this time, but it did change color quickly like Ruby Slippers. The longer I was outside, it got to a darker purple. Simply gorgeous.
I can't wait to try the others!
