A green filter will transmit green light by allowing only green wavelengths to pass through while absorbing other wavelengths.
When red light passes through a green filter, the filter absorbs the red light because it is not the same wavelength as the green light the filter is designed to transmit. The green filter only allows green light to pass through while absorbing or blocking other colors like red.
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.
A yellow filter will allow yellow light to pass through easily. It will also transmit some red and green light, but will block out blue light.
Filters don't change the color of light. They selectively absorb or transmit light based on its color. Anything that comes out of a filter must have been there before the light entered the filter.
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.

There are basically two different kinds of filters. The first kind belongs to the family of transition filters meaning that the only green light can come thought. The second one is absorption filter which passes everything though except the green light.
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.
Only the green portion of the white light would pass through the green filter. The filter absorbs all colors except green, allowing only green light to pass through.
you use a green filter in front of the light and you should just get green light passing through as all the other colours are absorbed by the filter. the filter would just be a sort of plastic thing which is green in colour :)
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.
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.
White light is actually composed of red, green, and blue in approximately equal proportions. A green filter allows the green light to pass through it, while absorbing red and blue wavelengths. Hence you seen green. You'll also notice that the intensity of the light is reduced when viewed through the filter because of the abroption of the other colors.
When a green filter is used, it will absorb red and blue light, allowing only green light to pass through.
