Trivia: Stop signs feature what two colors?
Blue and yellow
Green and black
Red and white
Purple and brown
The correct answer is Red and white
So why is this answer correct? : The first stop sign appeared in Detroit, Michigan, in 1915. Initially, a variety of colors were used, such as yellow and black. However, in 1954, stop sign colors were standardized to red and white. This was done for a few reasons, including that yellow is the primary color of warning signs and red is the color of brake lights and other stopping signals. Additionally, a fade-resistant red paint color didn’t exist until the mid-1950s.
