Natural light, the size of the windows, other lighting and orientation are some of the points that can influence the choice of floor colour. A dark floor "swallows" a lot of light, and also affects the feeling of space. At the same time, a dark floor can create a warm and comfortable feel in large rooms. A light rug on a dark floor unites the room with its light-coloured walls.

A light wood floor reflects the light and increases the feeling of space within the room, and can create a dramatic contrast to dark design details.

Polished and shiny floors reflect sunlight and redistribute it more than matt lacquered or natural oiled floors.
