As other commenters here have noted, I found this interesting but a little frustrating. The second color it asks about is clearly cyan (or turquoise). For me, this is like showing an orange screen and asking if it is red or yellow.

I understand that across cultures "orange" does not exist as a distinctly named color (it only got its name in most European languages around the 1500s), but as someone who was trained since preschool that orange is a distinct color, it would feel wrong to "round" it to red or yellow.

I haven't had green-cyan-blue drilled into me the same way as red-orange-yellow. So sometimes I do "round" it. I might note how "green" some cyan river water is, or call something cyan "blue" when it is next to something kelly green. But when I just have a screenfull of pure cyan light, I don't know what else to call it.

As a side note, I do wonder how differently a child would perceive color if they were taught more than 7 colors in preschool.

I was having a discussion closely related to this recently because of my background in philosophy of language. Languages are functional, but not rigid. The rules and referents of "blue" become kind of pointless around the edges, and narrow words like cyan or turquoise -- even words borrowed from other languages -- are more functional. This is exaggerated further when the functionality becomes very important, which is where technical jargon starts to come into play. Languages should useful to the speaker; they do not define the constraints of the speaker. "Blue" is useful for the average English speaker, but completely useless for a graphic designer.

Logically I understand that cyan is directly between green and blue, but my brain believes it's 100% blue.

I mean, that's the whole point of this exercise. In reality there is no hard line between green and blue, and if you make someone pick, their line is going to be entirely subjective, and different than others.

Not only that but once you pick green or blue it's going to skew your results in that direction. I got a higher level of blue as my result but it's only because that's what I picked since I had to pick one of them.

I’m aware of cyan, of course, but it never occurred to me while doing this quiz, because the point was clearly to choose between blue and green. Of course there’s cyan, turquoise, teal, sky blue, etc., but the point is to make the potentially difficult choice between only blue and green.

Also, as it happens, I feel like cyan is just not really in our everyday vocabulary if you’re assigning colors to everyday objects. Maybe it’s because it’s rare to see something truly that bright and saturated. I feel like in practice I would end up just saying “blue-green” more than cyan, turquoise, teal, etc.

Came here to say the same thing.

Like, I'd be interested to see if where my boundaries between blue and cyan, or cyan and green, are compared to the rest of the population.

But there's a whole other color between blue and green! A color that is primary under the subtractive CMYK model.

And it's an even bigger difference than with orange, because while red and yellow are 60° apart on the color wheel so that orange is 30° from each, blue and green are a full 120° apart on the color wheel, with cyan being 60° from each. So it's actually even worse -- it's as bad/nonsensical as showing yellow and asking if yellow is red or green.

it's either blue, or it's green. pick a side, coward

This was exactly my issue. There was no perception issue I could clearly identify the intermediate color as neither truly blue or green.

Taught by whom? I hear parents are wonderful teachers.

Also, lots of kids don't even go to preschool.
