Cyan is just another shade of blue to me. The colour you get when you google image search "cyan" is definitely more blue than green to my eyes.
Same as chartreuse and turquoise just getting called a weird shade of green, names affect perception.
Worse, if you call cyan blue, turquoise may become a weird shade of blue too, even though it's not even close.
RGB values are an arbitrary color coordinate system which does not match up 1:1 with human language.
