Is my blue your blue? | Hacker News

Hacker News users discussed an online test that estimates each person’s boundary between blue and green.

People shared results and debated whether borderline shades should be called blue, green, cyan, or turquoise.

The thread highlighted how subjective color naming can be, even for a simple-looking vision test.

Many questioned how much screen calibration, lighting, Night Shift, and True Tone affect the outcome.
