well, it's impossible to see the world through another person's eyes... so, it's impossible to say we see it the same or different.
But blue for everybody is the same thing... I see blue, you see blue, so it's blue. Just like anything else we decipher with our eyes, I see a fat lady, you see a fat lady, does that mean my concept of what fat is may be reversed and what I see you would describe as skinny? No way to ever find out... but as long as we say it's the same thing, chances, it's the same thing
What it is, is what it is...
