colour of any object is appeared by the colour of light which it reflects.
green grass appears green because, when white light is incident on it it reflects only green light and absorbs rest. so it appears green.
but if yellow light is incident on it, then it will not reflect any and absorb yellow. so as it will not reflect any , it will appear black.
