After use of easymotion colors look muted. On the screenshot I color picked the same pixel before and after use of easymotion, the hex values do not match. Even with the naked eye you can see that the colors different. After changing editor tab, colors looks normal again.

Is this happening every time you use easymotion or just sometimes?
This is happening every time. I decided to test it against different file types. I see this behavior with .py, .js, .css files, but .html, .md and .json are not affected. I tried changing the setting 'Easymotion Dim Background', but it has no effect on this.
It happens even with "vim.easymotionDimBackground": false? (I was almost sure this was related to the filter: grayscale(1) when using the dim background)
I'm currently making some changes to the easymotion default look, I have another suspicion of what might be making that. When I have a working version I will tell you so you can test it to see if it fixes this.
@Technik-J
Can you check PR #5108 to see if it fixes this for you?
This fixes it. Thank you.
