How to change the highlight color in autocomplete box in Eclipse

Question

I can\'t find a way to change the color of the highlighted selection in the autocomplete box in Eclipse.

Answer 1

for Ubuntu 12.04, simply edit the file /usr/share/themes/Ambiance/gtk-2.0/gtkrc search for

  base[ACTIVE]      = shade (0.94, @bg_color)

change the shade percentage from 0.94 to whatever visible like 0.54

  base[ACTIVE]      = shade (0.54, @bg_color)

then it works.
