🟢 50 Shades of... Green!

We know that people perceive colors differently. This is due to physiology, as well as cultural and linguistic peculiarities. 

The AI developer, a visual neuroscientist from the UK, Dr. Patrick Mineault, created a website powered by Claude 3.5 Sonnet from Anthropic. The site offers to test your perception of shades of blue and green. It has gone viral, with over 1.5 million clicks since its launch in late August. 

🔷 How it works

The test shows a series of six shades and asks whether you think each is blue or green. All colors are similar in range and only slightly differ in hue each time. 

The service uses the HSL (Hue, Saturation, Lightness) color model to evaluate hue perception. Each hue in HSL is assigned a number. For example, 120 is green, and 240 is blue. The test focuses on blue-green hues between 150 and 210. For most people, the result will fluctuate around 175.

The test shows where your blue-green boundary sits and how it compares to others who have taken it. For example: "Your boundary is at hue 176, bluer than 75% of the population. For you, turquoise is green."

Getting outlier results doesn't mean there's anything wrong with your vision. It might mean you have a distinctive way of naming colors or that your monitor and lighting are unusual.

⚠️ If you decide to take the test with friends, use the same device: color perception also changes depending on screen brightness and lighting.
