Color is so strongly associated with emotion, and I feel like red exemplifies these connections the most. Though used to convey a wide variety of feelings – hate, love, anger, danger, passion – red stands out in its ability to evoke all of them with equal force depending on the context.
The red of brake lights normally conveys a sense of danger and urgency, but close up, it takes on a more beautiful, mysterious quality. I enjoy red. Definitely in my top 3 favorite colors.
