The song "Wilma's Rainbow" by Helmet is open to interpretation and subject to personal analysis. However, based on the provided lyrics, the song seemingly tells the story of a person who is boastful, talks excessively, and pretends to know more than they actually do. This character is described as mentally endowed, indicating that they believe themselves to be highly intelligent or capable. The lyrics then mention a "watershed year" when this person becomes particularly ambitious or driven ("flush with fever"). They are referred to as the "richest junk dealer," which can be interpreted as someone who acquires and sells worthless or superficial things but succeeds financially. The mention of reading a book that allows them to think in rhyme may suggest that this person has gained a new perspective or way of expressing themselves. However, the lyrics also imply that their newfound knowledge is not original or profound, as it is described as an "old extreme" that has been repeated and imitated countless times. The song then introduces the character Wilma and her "rainbow of peaceful colors." The meaning behind this phrase is not explicitly stated, but it can be interpreted as a symbol of diversity, harmony, or acceptance. The juxtaposition of Wilma's rainbow with the previously mentioned "richest junk dealer" may suggest that material wealth and superficiality pale in comparison to the value of embracing diversity and peace. Overall, "Wilma's Rainbow" seems to critique and question the authenticity or worth of wealth and pretentiousness, while advocating for the importance of acceptance and harmony. However, interpretations may vary, and the listener is ultimately encouraged to find their own meaning in the song's lyrics.
