I chose to look at purple for this exercise. According to Incredible @rt Department, purple has connotations with transformation.
I also found that websites related to creativity use purple somewhat frequently. These also use white text for emphasis, with black
being for standard text. I found these examples in Musli - Design Inspiration.
According to Verywellmind's article, purple can also represent wisdom and bravery. Additionally, since purple dyes were historically
hard to manufacture and therefore expensive, purple can also represent wealth and royalty.
