Childrens rooms should be a bit of fun and for sure a bit stimulating and IMO gray is neither of those things. This is a childs space make sure you remmber that. The picture where the woman is holding the baby could be interesting

For my kid's room I found an edging at a big box store that was flat on one edge and curvy on the other. I painted the lower wall a darker green and the upper wall a lighter green. I then nailed the wood to the wall as if it were the top piece of a wainscotting (?). I thought it looked pretty good especially for how easy it was to do.

What furnishing materials and flooring are in the space as impacts the color? Photo of the space is helpful.

What is your 2 year old's favorite color?

I love green. It's earthy and pretty and can be dark or light. Can be outdoorsy, or calming, or vibrant. Can be paired with blue or yellow or orange or red. And, gender neutral.

Thanks for the ideas, keep them coming! The room is empty right now as it is new construction, but I can post a picture of her room in our current place later tonight.

Bright colors with lots of contrast are very good for developing eye coordination. Helping babies to focus etcetera. Primary colors are always good. Maybe paint the walls a cheerful yellow with bright red curtains and blue Linens Etc. I do know one young mother who painted her baby's room white with all black accessories. Her logic was that that was the highest contrast a person can get LOL.

Thanks, My wife isn't much of a fan of the greens and yellows.. any other ideas?

Still not knowing the flooring and furnishing materials I can suggest either a nice white/cream neutral or gray depending on the furnishings of the space. Your children's artwork framed is a perfect way to display colorful masterpieces and add color and texture to the room.

Thanks. Sorry forgot to post the pic. Here it is:

Great view! How about something very colorful? You could add a single bed in the space. This is one color pallet that is bright and happy. If you prefer not to paint the ceiling a deep color you could use the colors on different walls.

Here is another one that could work well - bright colors brought in through accessories and art but the wall color is stimulating too IMO

I would use stripes. One side could be grey/white with a pink stripe in the center, other side with a blue stripe. Or just grey and white stripe with different color accessories on wither side.
