Is the blue and white porcelain carp real?

The blue and white porcelain koi fish are fake, special effects. In 2019, a video of a blue and white porcelain koi fish circulated on the Internet. A netizen posted a "blue and white porcelain koi fish" that was said to be worth millions of yuan. It was very gorgeous and attracted the attention of many people. However, some netizens who love photography pointed out that in the video, when the koi is close to the edge of the orange water basin, a light purple appears on the edge of the blue texture on its head. The combination of orange and blue should reflect green, and there is absolutely no possibility of purple. There is basically only one possibility for this purple color to appear: the hue of the video has been artificially adjusted in the post-production special effects software. A netizen with experience in raising fish also said after watching the video that the water basin in the video has a special name and is called a fish measuring basin or a standard basin. It also has special production specifications, and its material is fiberglass; the color is generally blue; there are also special measuring rulers on the side walls and bottom of the fish basin, and the units are in "parts" and "cm"; measuring fish basins There is also a white drainage hole designed at the bottom. Following the clues from netizens, I found the same fish bowl in the video on the online shopping software. As you can see from the product screenshots, except for the different colors of orange and blue, other details are almost the same. Merchants told reporters that this type of fish basins generally only produce blue fish basins, and almost never produce orange fish basins. So it can be concluded that special effects were used to adjust the hue of the entire video, causing the original red and white koi to turn blue.
