Sherwin Williams has some palette themes with colors that all play nice together. They was very helpful for me when I had to select paint colors for our whole house.

Sherwin WIlliams color palettes

Thank you for the help, I've actually done just that, found a lamp and some curtains that I love for my bedroom and I'm basing my bedroom around that. Come to think of it, I did something similar for my youngest daughters room. It's just the rest of the house that I'm having trouble figuring out. I think it's also because I'm not used to the space and I don't know how we live in it yet nor does my stuff fit well here. I am going to take some pictures of my different rooms and share them, hopefully somebody else will be able to help!

I tend to be a fan of green, so I'd like to incorporate green in one of my rooms. I think the kitchen should be some sort of brown as it is mostly white and painted brown now and I like the contrast except they only did one coat of paint when they should've done to and you can see through the paint and it's making me crazy.

For the rest of the living space I just don't know. Something neutral but not boring if that makes sense? Definitely warm and cozy.

For seafoam or mint green colors that work well with gray, I would recommend Quiet Moments or Palladian Blue. I have these in 2 bedrooms and they're very pretty.

If you want even more green, you might like Healing Aloe or Wythe Blue.

Normally I am perfectly fine living in a space for a little while before deciding what colors to paint but right now two large walls in our main living areas are dark brick red and it is just not my style. Red looks great in some spaces but our house has no overhead lighting so it just feels dark and Like a cave.

The entryway was a navy blue and the carpeting on the stairs is navy blue as well.

I used two Affinity colors in our current place..(if I'm not mistaken..it was several years ago). I used Kangaroo for master bedroom, and Driftwood for my daughter's room. Love them both till this very day. But I then I prefer colors that are a bit murkier, muddy, complex, and ever-changing. Not everybody does-colors are so personal. Also they might look totally different in your place than in mine, and for sure different from a sample on a paper, or on a screen, or in a jar..you'll need to try them all first in your rooms in your light.

Colors should flow, but since bedrooms are more private space, usually closed, sometimes on a different level than the rest of the house-you can go and be more free in your color choices when it comes the bedrooms. You can try and introduce other colors from your home palette a bit, in furnishings, art, etc. I'd pick a several colors within each of your daughter choices that you like too..then ask them to narrow it to 2 or 3..then try samples on the wall, look at it in different times of the day, etc., then decide.

PS my teenagers also prefer these kind of colors..purple gray, green gray..darker, murkier side..interesting.

PS just read the rest of the topic, and how you think about your living space color.. this Kangaroo and Driftwood are neutral but very far from being boring..Driftwood being on the warmer, darker side. Like, seriously darker, but still not too dark. Every color plays well with this Driftwood. It takes out the best of other colors. Amazing.

If i did it again I would go with the affinity colours...so easy, they all go! No weird undertones that you don't until after it's covering your whole house!

I agree that the Affinity colors make it easy to combine colors throughout the house without clashing undertones. They are grayed, which makes them go well with a lot of current fabrics and painted furniture choices.

I had actually looked at kangaroo and thought it was a pretty color. I like it. The truth is I like those sort of muddier colors too, I think they are softer and more soothing on the walls. But I don't know if that's OK for a Kids' Room? And then the other question I have is if I go with affinity colors for the majority of the house can I use other Benjamin Moore non affinity colors in the bedrooms?

Here are some random general pictures of the house. Please ignore the mess as I've not finished unpacking and settling in yet.

These two pictures are of the family room. It has a really weird flow since one big wall is taken up with the fireplace and the other big wall is the entryway to the room. On the other side of the brown bookshelf is the doorway to the kitchen and obviously across from that is the sliding glass doors.

Here's the entryway that used to be navy blue. You can still see the navy blue carpet on the stairs. We removed the wallpaper and primed.

This is the living room where we have the TV. We have the couch moved in closer to the TV to make the space cozier but so much of the room is wasted and it looks funky. I like how the couch feels in relation to the TV but I don't like the general flow of the room.

Here is the dining room as you can see it from the living room

And my favorite room the kitchen. My pictures are terrible but it's very bright in real life. And you can't tell from the picture but there are three different paint colors in this room.

Regarding your question about certain color in a kid's room..It's a very interesting topic, how colors influence us. On a general level, and individually too. For example when I was teenager I was totally enamored with purple. Deep purple. It seemed the most magical, mysterious color to me. But it took me many many years (and a life change) to actually try and use it in my home..

But I know one little boy-very boyish boy by the way-who also loves, just loves purple))

Involve your daughters after you make primary choice of several colors(as not to overwhelm them, especially if they're too young), and see how they feel regarding different colors.

PS I like your place..and your dog)) I think it has all the potential to be fab..especially if you have a lot of light-you can get away with so many things!

PPS I think you can use colors from any collection as long as you feel it's harmonious together, and gives you the mood you've wanted. Collections are a suggestion, not a rule..

Are you keeping the couches and the carpet and rugs in the two rooms? If so, make sure that they blend with whatever you try. I would use the wonderful rugs in your living room and dining room as inspiration for those rooms or even for the whole house. Shades of grayed green/blue would look very nice with your floors/carpet, wood furniture and brown couches. Then you could put a brown in the kitchen. Have fun--it will be beautiful!
