Colors are caused by the absorption of parts of the light which hits it and the reflection of other parts. This is what causes something to be a certain color. What we see with our our eyes is our perception of that color. Even if a color blind cannot tell if a green object is green, it is still green. The color blind person may think it's pink, but it's still green.
You are mixing up perception of color with the wavelength range corresponding to each labeled color. When people refer to a green car, they are not referring to the wavelength itself but rather to their perception of the color they see with their eyes in accordance with how colors are labeled.
Another example is beauty. You might see something as aesthetically beautiful, and that is a truth for you, but someone else might see the same thing as unpleasant to look at, and so that would be a truth to them. There need not be ultimate truth in every case.
