Question

what is the appearance of a cloth capable of absorbing cyan be when illuminated by yellow ilight

Answer 1

When a cloth that is capable of absorbing cyan light is illuminated by yellow light, the cloth will appear yellow. This is because the yellow light that is shining on the cloth will be reflected and scattered, while the cyan light is being absorbed by the fabric. As a result, the cloth will not reflect any cyan light, leaving only the yellow light visible to the observer.
