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 blue object would appear darker when viewed through a green filter because the green filter would absorb some of the blue light that the object reflects, resulting in a more subdued color.
A green object viewed through a blue filter would appear darker or black because the blue filter would absorb most of the green light, allowing very little to pass through. This lack of green light reaching our eyes makes the object appear darker and alters its color.
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.
What is true is that the light has a green component. That's why it appears green. The green light can get through. There may have been another or other colors of light present when the light entered the filter, but because the filter is green, the other colors were absorbed. Remember, if an object is a given color, it is that color because it reflects that color and absorbs all others.
I'm guessing it was probably the GREEN light, and that somehow it had something to do with why the filter was named a "GREEN" filter, and why when you looked at it, it looked GREEN.

If green light passes through a cyan filter, the filter will absorb some of the green light and allow the rest to pass through. The transmitted light will appear as a slightly dimmed green color due to the absorption of some of the green wavelengths by the filter.
A coloured fliter works by only allowing a certain section of the spectrum through the fliter. For example, if everything seen through a filter is green hued, then the filter only lets through green light.

When a yellow book is viewed through a green filter, the filter will absorb most of the yellow light but allow green light to pass through. As a result, the book may appear darker and its yellow color may become less vibrant when viewed through the green filter.
When a green filter is passed through light, it selectively absorbs all colors of light except green. This means that only green light passes through the filter, while other colors are absorbed. The result is that the light appears green in color after passing through the filter.
You would expect to see the object appear cyan in color because the cyan filter would absorb most of the colors in the white light spectrum except for shades of blue and green, which combine to create cyan.
