If I have coastal floral living room chairs can I use black picture

What are colors are in the room,and what are the exact colors in the furniture,what colors are the walls?

You can if you like them! You may want to consider matting them with one of the colors in the chair to tie everything together

Yes. I would keep the actual frame thinner, use a white mat around the print. A little black or a little red works in most rooms, no matter what style the rooms are; frequently those touches make the room POP. For the life of me, I really cannot EXPLAIN why they work so well, but they do. Have fun.

Every room should have a touch of black and using picture frames is a great way to do it~

Black makes things look classy. So a touch would be great.

Ooh, yes! That will give a retro vibe, like old Miami in the movies. 😇
