Yellow is a spring color, is it not?

In the cultural context of Punjab (India), an artistic work that had someone dressed in yellow --i.e. which emphasized they were dressed in yellow -- would very likely be setting the scene as springtime, and possibly evoking themes of joy, blossoming, birth.

Red relates to weddings and happiness. White relates to funerals and purity. Black has certain religious connotations. Green is Sufism. etc.
