>How do you even know that "everyone else" experiences colors the same as each other? Generally through measurement. Colors are just differences in electromagnetic wave frequency, change the electromagnetic wave frequency enough and you are out of “visual light rays” and into other types of rays (radio, gamma, x, etc...). Until people start “seeing” those other non visable light rays, we have some indication we are all seeing the same things (light waves). As to the “colors” of the various frequencies within the visual light wave spectrum, we may receive/interpret them differently (ie color blindness), but the wave frequencies are the same and it is us who work differently. That’s why we can have other objective factors and measurements (primary colors, mixing of colors, etc...) that suggest for the most part we are all seeing the visual light spectrum waves similarly. In otherwords if you and I saw the visual light wave differently it should be obviously once we start mixing colors to produce new colors (if you saw black and white where I saw blue and yellow, then you couldn’t see green - it would be black). Still your use of “experience” of colors likely is inheriently true we probably all do experience the colors differently (some are my favorites, those don’t need to be your favorites, some may trigger certain emotions in me and not in you) but that doesn’t change the fact that the electromagnetic wave is the same for both observers.
