What color scheme would you suggest for decor (furniture, accents etc.) on a medium gray engineering hardwood? It's a wide plank hickory that seems to reflect a myriad of shades depending on how the light hits it!

Would appreciate pictures for inspiration. Our style is contemporary-comfy or transitional with pops of color. All decor has to be kid-friendly.

I'm usually a modern-yet-warm-and-colorful decor kind of person, but I'm stumped with this gray hardwood, especially since the kitchen cabinets in this open-concept living/dining/kitchen space will be a dark gray shaker style.
