A friend asked me to google this question...

I tried it. It does not work on android nor iOS

@darksideplease I did it from windows. Maybe that is why it worked

Tried from win didn't work, pretty sure its fake

No it's not a fake, probably it's been fixed.
When you ask a question, Google look for trusted sources and the AI provide you an answer. The first trusted source for "green" is Wikipedia, and Wikipedia says "green is the color between blue and yellow". The question is "WHAT COLOR", so the AI search a color in the text, and the first color is blue.
Anyway now it's fixed

@crisz you mean the natural language parser not the AI.

It's not fixed and still occurs on iOS

Nope. Not fake.

Works on android chrome. Lmao I died

Is it because you spelled colour wrong?

Oh!

@darksideplease the natural language parser is an AI, isn't it?

@crisz define AI

Doesnt work on ubuntu 16 nor my android 5.1 :/

Found the explanation

Got a different result with "color" and "colour" from Google UK

Mexican here... I'm not mad, this is actually great :3
