Interactive color perception test reveals where your personal blue-green boundary falls relative to the broader population.
Key Takeaways
The test locates your hue boundary on a population curve, reporting a percentile like “bluer than 76% of the population.”
Blue-green perception varies significantly between individuals; the boundary is a spectrum position, not a fixed categorical line.
The test uses forced-choice comparisons to pinpoint the exact hue where you switch from calling a color blue to calling it green.
Hacker News Comment Review
Commenters agree the binary “blue vs green” framing is too coarse: teal and turquoise sit in between and do not map cleanly to either category, making the forced choice feel inaccurate for many test-takers.
There is no labeled “normal” point on the result curve, leaving users unsure how to interpret their percentile without a reference anchor for median population boundary.
Real-world anecdotes confirm the test’s premise: one commenter’s blue-green boundary was greener than 95% of people, which explained a recurring disagreement with their spouse over a house color.
Notable Comments
@percentcer: argues the second button should read “this is not blue” rather than “this is green” to avoid forcing a false categorical label on turquoise.
@diziet: “There are colors in between blue and green that are neither blue nor green!”
