do u think i should go with a blue grey and brown grey or a green grey, the choice is so hard haha

Can you post pictures? Room size, windows, other furniture, etc makes a difference in wall color ideas.

Glad you talked about the various hues of grey. Before you paint the whole wall, do a sample, and live with it in all times of day light and with the lighting you will use at night. Believe it or not, the type of bulb you use can change the color! Blue and brown are great together. Find one color to use in a VERY small way (like less than 10%) as a accent color. It could be as simple as a white or yellow!

HI Try a few decent size samples on the walls in both. Check through the day as light changes as the day goes by. As someone else commented even a light bulb can effect color. Great that your thinking ahead and planning that's great. Robin OC, Calif

Thanks everyone, we will try samples for sure. Never thought to catch different light. Sorry I do not have extra pictures as we just bought it and move in on the 25th of March.

For accent colors- coral, yellow, aqua or red all work well with greys.
