Removal of boxes “archives” and “Categories”

Hey

Im using a theme called color3 by Frank Schrijvers.

The problem I cant seem to fix, is how to remove the two permanent boxes that appear along with all my other chosen pages. The boxes are “categories” and “archives”. They dont show up in my pages options, and I cant find out what to change in the templates. Neither are there any way to remove them easily through theme-options.

So if anyone can share abit of their expertise and help me out, I would greatly appreciate it.
