Are we to assume that you are contemplating a blue sofa? Sounds too complicated. Go with a more neutral color.

Yes. Especially since I love to change things around.

navy is a neutral color. if you are tired of all these boring and same look gray white or beige sofa, navy is a good way to go

I don't have one, but I would consider a colored sofa too. Following to see what people post!

Love my dark denim color velvet sofa. Kind of a transitional feel, 6 foot plus and deep. Club chairs are deep brown leather, paint is SW Windsor Greige, Only moved in last year, so room not done, need a piece over sofa, window treatments and the plants have to go elsewhere. The stained glass is 1920's rescued from a church and restored (the glass around the edge is blue though doesn't show well in pic.)

I love navy leather it is a neutral that works with almost every color, I did have a cobalt blue sofa in my last house but it was micro fiber and constantly full of cat hair so a friend bought it but I loved the color.

I think a navy or cobalt colored couch could be awesome, with the caveat that it shouldn't be too big and shouldn't be an oversized/overstuffed design, because then it would be overbearing.

Also, I think a small/subtle pattern in the material would help break up the monotony, just something like a patterned variation in material texture, not even color. I know it's all about solid color couches these days, but I think the right couch can look very good with a bit of a pattern. For years, my parents' couch was denim blue with a very small gold pattern on it. Worked just fine in the house at the time.
