Hi. It really depends on what type of look you like. I rather like the color interest.

You have nothing posted in your idea book, so I am not sure what your goals are.

The different colors definitely break up the long expanse and better define your space. On the other hand, if you are looking for a more light, open feeling, one color would be the way to go.

What you might want to consider is, rather than 3 colors, maybe just 2. If you choose 2, I would go with the orange and the green. I think the orange works well with the green as well as with the flooring.

I would have to see the artwork to say more about that. Too many colors and it looks bohemian. Nothing wrong with that, if that is the look you want.

Wall color is a personal choice. For me, this it is too bright for your rooms...it is all you see..the wall color. I would paint them all the same color and make it either a lighter shade or if this dark, less vivid. In other words, grays in this color tone would be OK because they are not bright. I, however would choose a more muted tone. Put your bright colors in large rugs under the dining table and the living room, drapery panels on the windows, accents on the sofa. It will ease the eye. A nice mid tone gray green, maybe. (Sherwin Williams "Cucumber" #6722) or any color just see how this is toned down. Colors always look darker & brighter on the wall. Before you change a color, purchase samples and paint them on posterboards and tape them to the walls and look at them in daylight and lamp light. Look at this feature that SW paints (and all the others have) to up load one of your pictures you can them choose paint colors and see how they look in your room. https://www.sherwin-williams.com/visualizer/#

Just that you are asking this question says maybe you feel the same way.

Love the orange and green. Personally, I'd tone down the yellow in the kitchen or repeat the orange, but that's just me. Color is personal...I love that you are taking risks and staying away from the standard gray and beige!

Are you just getting set up? Wonder about the drapes and odd positioning of furniture in the room.

Your best bet is to look on Houzz for photos of rooms you like. Post them here or on your idea book and that will tell all of us if you are headed in the right direction.

I love the color scheme you have selected. Its very energetic which is awesome.

Use softer colors to tone down the wall colors just a bit. Also (if the budget allows) continue the same color wood flooring that is in the other part of the house.to tone down the yellow in the kitchen. I would consider different color furniture in the room with orange walls. Add rugs to finish off the look along with your art work. I hope this will help.

Thanks all. I'm new at this - it's hard for me to get a good shot of the living area. I've attached another photo that was taken from the living room couch. the kitchen is not yellow, it's almost the same shade of orange as the living room. the only colorful artwork I have on the wall is the painting you see. rest is all artwork in brown. I love colors myself, just wanted to get other perspectives though - sometimes I feel like I go overboard with color.

Hi! Looks like you have a lovely space! Where the wall sconces are by your dining room table, could you hang some art work like this to bring all of the colors together?
