Photo that changes color on WhatsApp: understand technology behind magic | Social networks

Another photo became a sensation on WhatsApp. The image is simple: a mouth partially covered by three fingers with nails painted in the same shade as lipstick. However, the makeup and nail polish change color according to the action taken by the user in the messaging application. The file is accompanied by a text, which informs that it is a magical photo, supposedly created by engineers from Bangalore, India, and shared for the first time in the history of the app.

The dynamics are as follows: when receiving it, before lowering, the nail polish and lipstick look red. When downloading the image to the cell phone, the tone becomes pink. When you touch it and open it in a part window, the colors change to wine. If you forward, the makeup gets a greenish tone.

The explanation of the mystery is not about magic, but about technology. The image has a large PNG, a format that allows you to add transparency elements. In the case of the photo with the lips and nails, the transparency was applied only to the mouth and on the nails the tones change according to the color of the background in which they are inserted.

So much so that the trick also works when the image with the same format is saved in the gallery of a smartphone. In the example below, the thumbnail is pinkish due to the white background. When opened, it gains wine color as it is on a black background.

Other photos move the network

This is not the first time that an apparently simple photograph has mobilized the messenger users. In 2015, the photo of a dress was shared around the world and everyone just wanted to know one thing: was the piece blue and black or white and gold? Each person perceived the combination of colors in a different way and, sometimes, the same person could see both options at different times.

In 2017, it was the turn of a sneaker to become popular, dividing users between those who saw it in green and gray and others in pink and white. Recently, two other photos have been moving the Internet: in one of them, the challenge is to try to understand if the image is a transparent car or mirror, and in another, the question was to understand if the file had a blue door with a green border or the view of a beach.
