Have you considered a decal? They are easy to apply and can be changed as your child's interests evolve.

As suggested above, decals may be easier to update as the child grows.

I love that you're considering orange as a color for your nursery. Bright colors are great for infants. Including many colors in the nursery helps your child learn to differentiate the colors.

Here are three nurseries I found on the internet that use orange. I chose these because they would require the least amount of painting since they already have grey walls. Adding the orange through the accessories and soft items like pillows, stuffed animals, and bedding allows you to change it later just in case you decide you were overly influenced by the pumpkin spice time of year. :)

Just remember as baby grows and stands up in his crib, whatever you have on the wall will be the first thing he grabs....A decal seems best to me.
