is it possible to dull (gray out ) the background while searching

[mohitleo9]

Hey,
I use vim-easymotion's n-search feature instead of regular search (/). I find a lot of things very useful in incsearch and want to switch. But one thing that I am missing and I find really important is that when I am in easymotion and searching it grays out the background and thus bringing the search to utmost attention (kinda like safari search). I was wondering if there is a way to achieve similar behaviour in this plugin.
