The colour of an opaque object is due to the colour it

The colour of an opaque object arises from the wavelengths of visible light that it returns to the eye — in other words, the light it reflects. When white light strikes an object, certain wavelengths are absorbed by the material while others are reflected; the reflected spectral components determine the colour we perceive [1]. Opaque materials do not transmit light, so refraction/transmission are not responsible for their apparent colour. Scattering can affect appearance for particulate or very rough surfaces, but for most solid opaque objects the dominant factor is the reflectance (including diffuse reflection) spectrum, with absorbed wavelengths removed from the reflected light [2]. Therefore, the correct choice is: reflects.
