I like it if you want to stick with neutrals! As long as the colors are the same undertone as most of everything else. It's kind of hard to tell. However, a nice accent color could be really nice, like a red or deep red as in the coloring on the vase, and books,and lettering in art! That could really make everything "pop"!

I have neutral colors through out the whole house . I know to many people it can be boring but for me is soothing and relaxing . I did try to have some colors and I'm still frame and wall art shopping ... Thank you for your advise
