Is the Red You See Also My Red? (Colorblind Paradox / Inverted Spectrum)

If your perception of colors was the exact opposite of everyone else's in the world, but you were never discovered your entire life, would you be considered a 'normal person'? - The Colorblind Paradox Scenario Story: Kobayashi was born with a unique brain processing mechanism. From childhood, whenever people pointed to a red apple or a red stop sign and said, 'This is red,' the signals Kobayashi's eyes received actually appeared as 'green' in his brain, and when he saw green trees or grass, he perceived it as 'red.' However, because everyone around him told him that the color of that apple was called 'red,' Kobayashi naturally labeled that subjective sensation as 'red.' Kobayashi grew up to become an excellent bus driver: • When he saw a red light, a green image would appear in his mind, but he knew it meant 'stop,' so he accurately applied the brakes every time, never having a violation or accident in decades. • He could pick ripe fruits at the market or design color schemes for company posters, and his judgments were always indistinguishable from the public's, with no one ever noticing anything unusual. The most fascinating and unsolvable aspect of the colorblind paradox is this: If a person's internal experience is completely inverted from the rest of the world's, yet they make no mistakes and cause no communication confusion or danger throughout their life, does this unprovable 'subjective difference' truly count as a defect in our real lives? Is the red you see truly the red in others' eyes? Question: How can you prove that you are not 'Kobayashi'?
