I know the perceived colour of an object depends on which wavelengths of the incoming light are reflected and not absorbed, which lead me to believe that it is impossible to be red or yellow… I think it should be green but I am not sure because I am having trouble understanding this…
[Physics] Given is an object which is cyan when illuminated with white light. What is the perceived colour of the object when illuminated with yellow light

Simply, if you have an object that appears Cyan in White light, then that must mean it absorbs Yellow and Magenta. If you then illuminate that object only with Yellow light, it will appear Black (dark) because the object absorbs Yellow light.
