I need to choose paint colors.

I think a light golden yellow would look nice.

And that is why they make sample sizes! Here is what I do. I pick up the free paint chips at the paint store in colors I like and think will work. Take them home and tape them to the walls in the rooms I wish to paint. Live with them a few days, look at them in all your lighting conditions - morning, mid-day, eening and night - lights on, lights off. Then start eliminating. When down to 3 to 5 colors, I go back and purchase paint samples. Smear them on the walls and do the same process till you find the color you love. If none thrill you, start over!

I love your ginger jar collection and the blues and white should give you inspiration. Cool white walls are the safe way to go, but I would incorporate the dark blue accents either on the trim, or add trim in that shade. Go with the same blue and white in a patterned drape or shade for the windows and chair seat pads. If I were really bold I would sand the finish on either the dark wood buffet or chairs and do a chalk paint finish in a coordinating blue. I think it would be stunning.

See if the color wheel helps you out!

I like to look on Sherwin Williams site here is a link i like the pic of the softer side,which appears to be a lighter yellow shade as well . https://www.sherwin-williams.com/homeowners/inspiration/find-and-explore-colors/hgtv-color-palettes

sherwin williams has a great color : Macadamia. I have used this color on several projects for clients and everyone who sees the final results love it. Be use to let your test sample dry completely as wet, this paint looks like mud.

I see you share my love of blue and white! Your house is lovely. I like red or a rosy color, or green as a background to the blue and white, but for myself, since my house is darkish, small rooms and no open plan, I use white paint. I used to belong to an HGTV forum on decorating and the designers on there suggested getting sample cans of paint and painting swaths at least 3' square and as Naomie says observing them in all light conditions. Good luck!

What ever color you choose you do need to paint all of the baseboards and ceiling moldings white..you have a lot of dark furniture and heavy looking drapes which eats up the light in the rooms...go for lighter sheers and a soft neutral shade for the walls..test colors as others have suggested..maybe eliminate some of the excess small furniture pieces in the corners of the rooms as well as knick knacks which clutter up and make the space feel smaller..

Also paint your brown windows white to flow with the white baseboards and ceiling moldings... will look like a totally different room!

A soft blue grey is always classy

I cannot tell on my screen what color your sofas are, but they seem neutral taupe or beige.... Today's trends would point you to greys, or sage greens, or soft blues.... Since you have earth tones started, you can spruce it up by adding the color backgrounds just mentioned.

Find out what you LOVE to have around you. Do you love vibrant color? Do you love very soft color? What colors do you wear? What colors make you happy or very soothing, when they are around you? I personally, am happiest when I have soft shades of green around me.

Yes I like this third photo incorporating the blue, but it does make the room seem dark. I would go with lighter wall color to bring in more light.

Love your blue and white pottery. Use a color wheel for ideas.

A light blue grey would look good
