One of the latest painting techniques on walls is to create small shadow games by making gradation with close tones of the same color! While different color shades add a sense of depth to spaces, they also change the aura of the space. For the shading technique, use two tones of one color and apply it by dividing the wall in half horizontally or vertically or diagonally. On the line in between, mix the two colors and fold it into each other until the sharp line disappears. If you want to add height to the room, the dark tone should be at the bottom and the lightest tone should be at the top.
