It was a long forgone conclusion that the suggestion to paint walls white would make them look bigger; whereas painting them darker would make the appear smaller. As it turns out, it is scientifically correct!

Color can have a significant effect on the size and appearance of a room when it is used in interior design. Some colors tend to make a room look larger or smaller, while others can create a sense of depth or openness.

Light colors tend to make a room look larger and more open, while dark colors can make a room feel smaller and more enclosed. This is because light colors reflect more light, which can make a space feel brighter and more open. Dark colors, on the other hand, absorb light, which can make a space feel darker and more intimate.

Using stripes on the walls can also affect the appearance of a room. Horizontal stripes can make a room look wider, while vertical stripes can make a room look taller. However, the effect of stripes on the size and appearance of a room can depend on the size and placement of the stripes, as well as the colors used.

Overall, the choice of color and use of patterns and stripes in interior design can have a significant impact on the size and appearance of a room, and it is important to consider these factors when designing an interior space.
