Does everyone truly see the world the same way you do? A seemingly simple color block image has recently exploded across X (formerly Twitter), sparking a massive debate. Composed of several vertical blocks in shades of purple and reddish-brown, it looks like a straightforward gradient at first glance. But the wildly varying number of colors people claim to see has turned it into an unexpected "eye test" challenge, even drawing in creators and professionals to the discussion.
The buzz kicked off when user " jade⁷ (@0UTR0EG0)" shared the image, asking how many colors others could spot. They confessed to seeing only 4, a revelation that immediately triggered a deluge of responses as countless users chimed in with their own observations.

One user, claiming excellent eyesight and years of studying color theory, stated they saw 11 distinct colors. They suggested the image serves as a fascinating case study for how humans differentiate subtle color variations.

▼Many users agreed on 11 colors.
The discussion quickly spilled over into the ACG (Anime, Comics, Games) creator community. Yuu Kamiya, the acclaimed mangaka behind "No Game No Life," weighed in, asserting his confidence in color perception. He calculated 12 distinct colors in the image under normal viewing conditions.
However, he added that if you factor in the noise generated at the block edges due to JPEG compression, the number of identifiable colors could easily exceed 20.

▼Renowned illustrator "lack" also counted 12 colors.

▼Some users even claimed to see a whopping 56 colors!
So, what's the "correct" answer? It likely boils down to individual visual acuity, viewing environment, and how one defines a "color." Our editor here spotted 12 – how many did you see?
