Painting: the optical effects that define or redefine a room
When it comes to interior design, the way you paint is very important. It is not enough to paint your walls with this or that color when you want to enjoy a beautiful interior. Indeed, before painting or refreshing the walls of a room, it is advisable to plan the work according to the size of the room and according to the optical effect that one wishes to obtain.

Expand the space
In a cramped room, it is best to use only white paint for the walls and ceiling. White attracts light which is beneficial for a narrow room. In addition, white gum room boundaries, which gives us the impression of being in a room more wide. To better accentuate the desired optical effect, it is preferable to have white soil.
Lower the ceiling
With a high ceiling that we want to lower by optical effect, clear walls and floor should be used for a colored ceiling dark. Consider incorporating LED spots or other types of ceiling lamps so that it does not darken the room. In addition, a dark painting that reflects the light would be better.
Stretch the piece up
If on the contrary, the part appears short, the best is to paint the walls with a dark color. As for the ceiling and the floor, paint them white. As the dark color dominates in this case, remember to light the room well.
Highlight a particular corner

When we want to highlight a particular corner (the fireplace, stairwell, office area, headboard, living room, etc.) you just have to paint the corresponding wall section. Make sure you take a color that you can associate with your highlight colors, that is to say with the colors of your furniture, etc.
Extend the room
To lengthen a room, the best thing to do is to paint the two side walls which go in the direction of the desired elongation.
Expand a room and better enhance the furniture
