How can we know if our perception of blue matches others?

I’ve been thinking about how we can ever truly know if our perception of the color blue is the same as someone else’s. I can describe it as the sky on a clear day, but that just points to another shared perception. It feels like a fundamental gap in shared experience that language can’t bridge.

I keep thinking of that moment when a friend and I stared at a white wall under different lamps, hoping the labels would line up. They didn't, not really. It felt like the wall was a map and we were using two different legends.

I did a quick experiment with swatches and a timer, trying to merge terms, but by the time we agreed on one label, the other thing looked different to me.

Maybe the problem isn’t the skin and eye but the shortcut language uses. Are we chasing a false uniformity, or is the real issue that we expect words to carry more weight than they should?

I remember walking through a gallery and noticing how the same shade can feel warm in one room and cool in another, depending on surrounding colors and the mood of the piece. The drift is that perception shifts in context, maybe more than we admit.
