Room decor that meets the purposes of non-church groups doesn't transfer to the church. Fantasy or make-believe characters have no place in a church facility. If there are such items, these items really need to be removed. Colors set the mood for the session. Colors add to the activity level of preschoolers and children.
Colors stimulate different responses from different people, i.e., red stimulates, blue soothes.
The accent color gives the appearance of shortening the room. The accent color should pick up a color in the carpet. Color is added to the room through the tables and chairs as well as the Bible pictures, verses, and games used in the session. Besides, we don't teach about Noah's Ark every Sunday or Wednesday. Also, a room that is used this church year by first and second graders many need to be used by fifth and sixth graders next year due to enrollment shifts.
