It will be black because there may not be any green light reflecting the green apple so if theres no light then it will become black
A green object appears black when viewed through a red filter (here a red filter means red light) because green object can only reflect green color and absorb all the other colors so in the red light it will definitely appear black.
It will look black, or green, depending on the hue of the red. A green filter blocks the red light but no red object is reflecting solely in the red wavelengths, and any non-red light will appear green through the filter.
A filter removes certain colors of light which pass through it. The primary colors of light are green red blue. Since the shirt absorbs all but blue light and the filter removes all but green it will appear black.

The blue filter allows only blue light to pass and blocks red and green light. The green filter allows only green light to pass and blocks red and blue light. Therefore, the two filters together block all light.
