The signifier in this picture is the lamp, which could signify different things to different people. For me, it conjures up an image of home and warmth, perhaps reading in a comfy chair. It also signifies light and hope; the large scale of the lamp to the table is symbolic of the importance of these ideas (of light and hope). For some people, the lamp could simply signify a lamp, and the bright colors could add to its symbolization of happiness.
