No, not objects that are opaque.
Color is reflected when light strikes an object and some wavelengths are absorbed while others are reflected. The reflected wavelengths determine the color that our eyes perceive. Objects appear white when all wavelengths are reflected, and black when all wavelengths are absorbed.
The color produced when objects reflect light depends on the wavelengths of light that are reflected. For example, an object that reflects all visible wavelengths of light appears white, while an object that absorbs all wavelengths appears black. Other colors are produced based on the specific wavelengths that are reflected.
Objects that reflect all colors of light appear white because they are reflecting the entire visible spectrum equally. When all colors are reflected, they combine to create white light. This is in contrast to objects that absorb all colors, which appear black because they are not reflecting any light.
Green is not reflected, but rather it is absorbed by objects. When we perceive an object as green, it means that the object is reflecting green light wavelengths and absorbing all others.
The "color" black is not really a color. Black is the absence of light. Black objects have pigments that absorb all light and, therefore, none is reflected for us to be able to see.
It's often possible to see non-luminous objects if you illuminate them with a source of light, such as a flashlight, a candle, or a drop of golden sunshine. No object absorbs all of the light that falls on it, so some light is always reflected from it, and some of that reflected light finds its way to your eye. Once any of the light falling on the object has reflected from it, it's very much as if the object were self-luminous.
Be careful not to confuse: Opaque objects are those that do not allow light to pass through it, but they can reflect light. It is BLACK objects that absorb all the incident light on it. To conclude, opaque objects do not necessarily absorb all the incident light on them but black objects ABSORB all the incident light on them (and are, of course, opaque)
When light bounces off an object, it reflects in all directions. Some of this reflected light enters our eyes and is processed by the brain, allowing us to perceive the object. The color and intensity of the light that is reflected determine how we see the object.
Light rays that are not reflected by an object are either absorbed or transmitted through the object. Absorption occurs when the object's material absorbs some of the light energy, converting it into heat. Transmission happens when the light passes through the object without being reflected or absorbed.
When objects reflect all light waves that strike them, they will appear white. This is because when all colors of light are reflected equally, they combine to create white light. On the other hand, a black object absorbs all light waves that strike it, so it appears black as no light is being reflected back.
The object would appear black. If it were literally absorbing all light and reflecting no light, then you'd be able to see it by contrast with the background... unless the background were also true black, in which case you couldn't see it at all.
The color of the object that you see will depend on the wavelengths of light that are reflected. Objects appear a certain color because they absorb certain wavelengths of light and reflect others. White light contains all colors of the spectrum, so the color you see is the result of the wavelengths that are reflected by the object.
