TWO DIFFERENT TEASERS ON ONE PAGE

Hi guys,
Usually people are looking for - how to make two different teasers on one page and I have the opposite problem. My TERMs pages display teasers from different nodes but I need to make them look similar (THE SAME). I thought I did it, at least teaser display options for each node seems to be the same but the real display of teaser is still different (one teasers are shown separately with blue backgrounds (that was the default for this node) but when I did new ones nodes - teasers for them are normal (with white background, separated with long horizontal lines). Where can I change it and make them looks alike?
Please help me, im trying to figure this out since a long time ago.

THANKS !!!
