Unlike the kitchen or bathroom where practical constraints like moisture and stains force you to stick to paint finishes like high-gloss, that is not the case for living room walls.
That being said, you are open to using the whole range of paint finishes – from high-gloss to matte, and more.
If you want to create a modern corner TV unit design for living room, you can direct people’s attention to the area by experimenting with colours, finishes, and textures. For example, you can go for a matte finish for wall texture paint designs for hall or a semi-gloss finish for a brick wall design.
