Eclipse syntax highlighting: how to configure same occurrence color properly

Eclipse has some nice syntax highlighting feature, especially with the popular add-on "Eclipse Color Theme" from the Market place. The result is pretty nice, at least for my taste:

(here the obsidian theme)
On very nice feature is the ability to highlight automatically same occurrences of same. Unfortunately as you see here the "follow" keyword is totally bloated and unreadable.
