Love your house. Not crazy about the green- I think a greige ( gray/beige) might compliment all the lovely wood. I think the chairs fit your log cabin home but not your style. You have a more modern vibe.

Here are some ideas:

What about red cabinets?

Yes I think it is time to change the green colour - greige would be good.

Also black dining chairs would look better. What about ones the same style as your computer/desk chair in pic 3.

Absolutely get a pro painter. We had our hallway going upstairs painted this summer- it ended up being much cheaper than we assumed and we LOVE the end result ( same thing- 18 foot ceiling)- he even painted the ceiling, the rest of the upstairs hall and trim and was way under $800 !

For paint how about a silvery gray?

well as beautiful as that is, i in no way meant for you to do anything you are uncomfortable with. I was giving you many options, maybe you just want a rug or two or the pillows. or the kitchen paint. Only you know what you are comfortable with. Do it only if you think your family is ready for it. I really do not want you to have more work. i think if i did any fabric with the chairs it would probably be in the form of chair pads? look great when noone is there, easy to replace?

drbevdc those chairs are wonderful! Look like they would stand up well with your kids!

These chairs are walnut and vinyl, love the black. They mimic your counter stools.

Mixed woods often happen with decorating done over time. I find if you have differing woods, if you can see each wood repeated in the space three times, you are ok. This Houzz article is worth a read.

Have you considered an area rug under your dining table as a transition between the wood floor and differing wood table?

In the 2nd photo, the walls are Sherwin Williams Functional Gray, looks nice with the pine. I don't know if this is considered a warm gray, but I think it may look great against your fireplace.

I had the same thought, a colour that's in the stones in the fireplace will look good. Also, go for a light colour.

Maybe go for Useful Gray SW 7050 or Worldly Gray 7043, they are a tad lighter on the same strips. Your house seems fairly dark, which is why I'm suggesting to go for lighter colours.

First off I am still giggling at your 50 Shades of Gray personal hell comment...I hear ya. I did try to 'paint' your room on the Sherwin Williams paint visualizer but the Amazing Gray and Analytical Gray didn't come up true in the photo ( looked too white) because of the lighting. I would strongly suggest you buy one gray sample paint like the Amazing Gray ( they are sure close) and then a true greige like SW Versatile Gray (which is just one shade lighter than SW Perfect Greige) paint and paint a few sections of you wall ( and especially near the fireplace). This will help you make the decision before your painter comes. Worth the $$ and it looks like Lowes ( if you are in the States and you have one near) sell the tiny samples- here is a link to Comfort Gray :http://www.lowes.com/pd_636697-678-HGSW3286_1z0yye3__?productId=50388842&pl=1

LOL- I'd paint all over the walls since you have a pro coming in to fix it. That way you can try the area next to the FP as well as under the stairs etc etc....

removed the pics to help unclutter. get lost on gray tones. have fun!

Just a suggestion, ask a 'color expert' or do your own research. If you choose a grey that has a cool undertone, it will make your wood look even more yellow or orange. I'm assuming you would not want that. If you choose a grey that has a warm undertone, your wood will look better. Look at your last photo, the walls around your cupboards and the stairwell. Green is a cool color, so the wood looks even more yellow/orange.

Don't put your paint samples on the green wall, you will never get a true 'read' on the grey color because your eye will see the green influence. If you have a piece of white primed drywall or an MDF board primed white etc, do that.

i totally get what you're saying about clashing wood tones. would you be willing to paint your cabinets? What i think i'd do....if it were my home... is minimize all wood except for structural (floor / ceiling / walls) and paint everything else - including walls,within a tight tonal palate. i like the ladderback chairs with the cabin style home. don't like the stools. i understand the black thing....and why you have them, but the style of them and them being black against the wood backdrop of the island...it draws too much attention and they're just not that interesting.

I see in your Fifty Shades of Gray photo, you have paint strips. They will help you eliminate. If the darkest colors on the strip look cool blue or green, don't use any on the strip. If they are a bit warmer or neutral, consider one on those strips. If you don't have the paint strip for your final choice, ask for it so you can see the 'base' color.
