Hi - thanks for the question!
The easiest way to coordinate the colors exactly is to look to the other colors on the same color strip as Gingerbread Man. For instance, you could use Tawny Bisque 1110 for walls and Hilton Head Cream 1107 for ceilings.

I also like Brandy Cream OC-4 for either a wall or ceiling.....whisper of color and so pretty!

Not sure what other colors you might be working with in your design, but pulling in a blue or green, maybe even a yellow, would be great too. If you'd like to tell me a bit more about your spaces/fabrics/furniture I can recommend some colors other than 'neutrals'. Feel free to upload photos too if you think that may help!
Thanks!
