If you say the trolley is blue, it goes straight, where there's a baby in the tracks. If the trolley is green, two grandmas die.

I feel like using only RGB values to define 'aqua' is a bit reductive as it is merely a specification in a specific environment trying to render a type of color but with inherent limitations such as not being able to reproduce the whole spectrum, color accuracy on the display, etc. etc. there's a lot of other parameters along with your own individual color perception that goes beyond "it's equal values blue and green within the RGB color-space"

But then as I list all these things I think I arrive at the same conclusion as you, it feels like a dumb false choice haha

Even if aqua is neither more green or more blue, wouldn't it be interesting if when given the choice, the outcome leans toward green or blue to a statistically significant degree? or perhaps that there are differences in how it's perceived based on measurable factors like geography, wealth, height, weight, etc?

Collecting data is how we learn, and discover new things. Even if it seems dumb to you.
