Ralph Lauren Sisal and Burlap are both very nice and nice together. One is much darker than the other. Looks nice with Ralph Lauren Throne as trim color. Tan/greys.

I would suggest a warm color for the kitchen and use the grays in the living room/ dining room area. All the colors that you mentioned are neutrals so any of them will go well with any of the other colors including your couch. Consider painting the kitchen a different color than the dining room and living room. Think about the golden sand color for the kitchen, and the light gray for the living room/ dining room. With the focal wall (in the living room) the darker gray. Your couch will pick up the colors of the walls in the kitchen and you grays will bring out the black of your counter tops. You could use the same color in the bathroom as you did in the kitchen, but accent it differently. Sirius Gray by Sherwin Williams is a very beautiful modern gray and it looks fantastic with a golden sand color, paint the trim white or leave it white. You could also use either one of the grays in the bedroom, the Sirius Gray is a moody color and it would look fantastic in a bedroom.

There's a blueish greenish grey called "Rainwashed" by Sherwin Williams that I love. You can get a sample at a Sherwin williams store.

Love your rug in your living room area :)

Love Rainwashed by SW! Since this is a small space I would keep all the colors similar but in different tones.

Revere Pewter for the light gray, Galveston Gray for the darker gray, and Grant beige for the beige/tan color. All colors are by Benjamin Moore. Hope that helps.

After reading all of the above, there are other colour alternatives that are not gray or beige. The trick to this is to have a range of colour in the same value tones. The bathroom can be darker- as your fixtures and cabinetry are lighter. Remember, lighting and your skin tone...in the luu.
Lighting changes the mood and affects all the colours in the space...so ensure that you have large enough samples to test the colours- in all lights of the day. Do not paint your walls- paint some art board or get the huge chips.

What is your favourite colour?
What colours do you love? What colours calm you? What colour makes you happiest?
You have a very neutral palette- excluding the fabulous area rug! You can have some fun and colour block...

Personally, I find gray depressing and beige boring...thus, I find that a great white- Benjamin Moore's Vanilla Milkshake, Oxford white ( great for base and trim) are a nice match- brighter than the others...once again- colour is a personal thing.

I also subscribe to the fact that we live in a colour rich world and we need to be less afraid of using it in our interior spaces....So go and get some colour that you love...not the rest of the world...It's your home...not ours.
