Showroom lights and bright afternoon sun can make almost any floor look lively and attractive. But on a rainy, grey day or at night under warm artificial lighting, some colours can suddenly feel dull, flat or even gloomy.
Imagining (or testing with samples) how the floor will read in lower light conditions helps you avoid picking something that only looks good a few hours a day.
Since you’ll spend plenty of time at home when it’s not bright and sunny, you want a tone that still feels pleasant and not depressing in those softer conditions.
