According to the Pantone Institute, the organization that forecasts global color trends and advises companies on color in brand identity and product development, the Color of the Year 2018 is ultra violet. On Pantone's website they explain how ultra violet relates to ideas of "originality, ingenuity, and visionary thinking that points us toward the future" and they mention how this color has long symbolized mystery and mysticism. I doubt that the driver of this taxi was considering any of this when he customized the interior of his cab with ultra violet vinyl seats, but I can tell you that this color definitely creates a distinct mood in the taxi.
