I’m sure most of us agree that the colour yellow packs quite a visible punch. It’s bright, it’s eye-catching, and one of the most visible colours on the spectrum. Interestingly, a lot of people will actually see yellow before they see any other colour, and when it’s combined with black, it’s a knock-out combination. Take the iconic New York cab for instance. Bright yellow and visible from a distance; it’s hard not to focus your eyes on the bright shiny vehicle sporting such a loud hue.
