The flagman, who typically stands above the race track and at the start-finish line in what is informally referred to as the “crow’s nest,” is essentially the race controller and chief flag waver. There are 15 different flags or flag combinations (two flags that are waved together at the same time).
#Green red and black flag drivers
Cars and drivers on the track must adhere to each flag, lest they be waved off-track and disqualified (black flag with an ‘x’ stripe).
#Green red and black flag driver
Blue with Yellow Diagonal Stripe – leaders approaching a lapped driver.Checkered (Green) – race stage has ended.Checkered (Black and White) – race has ended.Green – start race or continue race under normal conditions.Here’s a quick guide to what each NASCAR flag you’re likely to see means:

It’s an interesting exercise, well-executed by Jasper Johns’ painting from nearly five decades ago.Flags are among the most crucial elements of all NASCAR races. Thus, Jasper Johns’ optical illusion works perfectly to recreate the colors of our American flag. On the color wheel, the colors directly opposite of green and orange are red and blue. When we first look away, our eyes briefly see the exact opposite of those colors because different, fresh visual receptors are stimulated. More precisely, cone cells sensitive to the color differences between red/green and blue/orange are overstimulated and get tired. The optical illusion occurs because, after staring intently at a group of colors for an extended period of time, the color receptors in our eyes that recognize those specific colors become fatigued. (If it doesn’t work the first time, try again, focusing even more intently on the green, orange and black flag.)

Magically, as you lower your focus to the bottom flag, a familiar red, white and blue color scheme will appear to float faintly atop the gray flag. Jasper Johns, “Flags,” lithograph with stamps (1968) Then, close your eyes briefly and lower your gaze to focus immediately on the black dot at the center of the gray flag painted below it. Focus your gaze on the white dot in the middle of the image, and keep staring at it for a solid 60 seconds. First, stare intently at the top flag, the one in green, orange and black. Jasper Johns’ 1968 painting “Flags” depicts two flags in radically different color schemes from the traditional red, white and blue of the American flag. Let’s examine the optics behind one of the artist’s iconic paintings. “I am interested in how we see and why we see the way we do.”Īs an optometrist, I am also interested in how and why we see the way we do. I am interested in the idea of sight, in the use of the eye,” Johns explained. “I wanted to make people see something new. In the 1950s, American artist Jasper Johns began painting familiar objects such as flags, maps and numbers, in unique ways to inspire a reexamination of iconic images. The American flag is a well-known icon worldwide, and is often depicted in paintings. It’s the 100th anniversary of Flag Day, celebrated each June 14 since the 1880s but not officially recognized as a holiday until President Woodrow Wilson proclaimed it such on May 30, 1916.
