Blanche prefers darkness and avoids direct light, which equates darkness with lack of romance and danger. The naked lightbulb in the Kowalski's apartment may symbolize harsh reality and truth. When Stanley smashes all the lightbulbs during his first night with Stella, it signifies his rejection of illusion. The "colored lights" Stella likes refer to places that mask the truth. The bright light when Blanche reminisces about her husband's suicide represents harsh reality penetrating her fantasies. The candles on Blanche's birthday cake, and her blowing them out, suggest the passage of time and inevitable fading of youth. Blanche uses light as a metaphor for both romantic awakening and the shattering of illusions
