We observed all the signs from the Rialto Bridge leading to San Marco Piazza, which we recorded in the image below.
The blue mark means that the sign was easy to follow, the red mark with a "x" means that a sign should be there due to the possibility that someone can get lost, and the grey mark means that the sign cannot be understood well due to a homemade sign made from non-wooden material like paper or that the color of sign makes it difficult to read it.
