Decorating and Design - Colors & Accessories

I am redoing my kitchen, family room & living room. They all are open to each other. The kitchen & living room will have an oak laminate floor. The kitchen is taupe with a granite look countertop with taupe & grey (Wilson Art Mystique Mount), stainless appliances. The living room is Sherwin Williams Connected Gray which really has a olive drab look to it. The living room has a large brick fireplace. The family room has 3 walls that are brick and one wall is painted Sherwin Williams Techno Gray. (gray green color) The floor is a quarry tile in tan & dk red.

I am to the point of window coverings, furniture and accessories. Need to pick accessory colors for these rooms or a few colors to use in each room. Any good websites to check out???? I have had suggestions of plum, blue, terra cotta. Any suggestions appreciated.
