Objects don’t “have” colors either, if we’re being pedantic. They reflect/absorb/transmit/emit different combinations of wavelengths. So “pink” objects just reflect some wavelengths that we classify as in the range of “red” and “blue”. Color is an interaction between emission, detection, and the brain’s interpretation.

Its not even a unique trick. The ears combine various wavelengths of air vibrations to create sound, with combinations of pure waves merging into distinct timbres (sometimes called “tonal color”).
