And as the photo went viral, different reactions started pouring in. One of the comments read, "For me, the green and blue lines work the best and seamlessly blend into the background. Red looks like a grid on a grey background."

Some of them also went into the details of the picture and explained the science behind it. One of the comments read, Yes, and I think it's because the contrast between the red and dark colored shirt is greater than that of any other color combination in the picture. I know the human eye can see more shades of green than any other color, but I'd imagine we see red more quickly because it implies danger (same color as blood)."

Here's another explanation to the effect by a Reddit user: " As an artist, it's because Red is a warm color. Colors like Blue are cold colors, and tend to recede. There's some scientific reason about wavelengths and how our eyes adjust, but I don't really know the ins and outs so i'll leave it to someone else to better explain. This is why things like Stop Signs are red. And Yield Signs are Yellow. Both warm colors, easier to catch the eye.

The photo continues to go viral and has received innumerable reactions. People continue to comment on it explaining what they think caused the effect. Various such photos creating optical effect has always amused social media users in the past.
