I’ve had some of the same concerns about dark…showing dirt. I have two dogs ( boxers) and pet hair is a concern. If I had lighter cabinets, the dark floors would be an easy choice to me...despite the extra cleaning. I’m leaning towards dark right now.
The main counter space is a lighter polished granite, while the island is a darker honed quartz. My original thought was that if I go dark and it feels to dark, I’ll have the island painted a lighter color.
My builder has this weird thing about lighting…he likes to minimize shadows in the house, so he adds lots of lighting ( artificial). This house doesn’t have a lot of windows, and the biggest windows face north/south. The entire west side of the house has no windows. It’s a three story house right outside of downtown (very small lot)
