Right click pop-up menu

[looloo86]

I used this "Border#JumpListRestyledAcrylic" as the target and I was able to change the color and opacity of the right-click menu. However, when the pop-up menu goes back down, there it shows another color. For example, I set it to purple for when the right-click menu pops up, but when it goes back down it is a different shade of purple. What should I target for the animation of the menu going back down?
