Well. Mostly I wonder like... What if the sky is actually a different color? But like to all of us. Like we totally see the world different from each other. But since language is so restrictive we can't really convey the 100% true meaning of outlr thoughts and experiences so we fall back to what we learned in preschool. 

So I see Green and you see orange but we both call it blue because we learned that color is blue. 

I'll take my sat plz.  

 I can taste colors, so....ya. possibly.
