unequal bottom-margin in right-click menu on colour selector

[Ezra Sharp]

Just a little thing but it annoys me every-time I see it.

The margin above and below the file-name colour selector is different, half on the bottom what it is on top.

Se screenshot, some other options do this too in places.
