In the light or against the wall?
TO THE LIGHT
The bubble panel looks most interesting in the light, when a panorama opens through it, there is movement, etc. Due to the refraction of light, the picture is slightly distorted and looks beautiful and unusual. But all the contours are easy to guess. Can be used as walls for meeting rooms, zoning for cafes, etc. If you need to reduce the degree of transparency, you can apply a frosted film to the panel or install frosted glass.
TO THE WALL
If you plan to install the bubble panel against a wall, then the best option is a mirror or black background. A mirrored background looks better in dark rooms, black is better for bright ones.
