Translucent

Allowing some light to pass through, but greatly obscuring the image of objects on the other side. A quality that is between transparent and opaque. Materials that may be translucent include glass, papers such as glassine, plastics such as Lucite and PlexiGlas, and porcelain. It is quite possible for one person to describe something as translucent if it is merely tinted, and for another to describe it as transparent because it is so easy to see through it clearly.
