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.
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.
It depends on what kind of filter, e.g. a blue filter absorbs everything except blue light, so only blue light comes out, which is why the filter looks blue, and is referred to as a "blue filter".
The color of light that passes through a filter depends on the properties of the filter. If the filter is red, only red light will pass through. If the filter is blue, only blue light will pass through, and so on.
Well, honey, the light that does not come through a colored filter is the one that matches the color of the filter. So if you slap on a red filter, the red light is gonna be like "nah, I'm good" and stay put. It's like trying to wear a red shirt through a red filter - not gonna see much of a difference, darling.

If you put a blue filter in the path of a ray of light, the filter would absorb all colors of light except for blue. This would result in the light passing through the filter appearing blue in color.
If you place a blue filter in the path of light coming through a red filter, the blue filter will absorb or block the red light, potentially resulting in less intense light or a different color of light that is transmitted through. The combination of the two filters will likely produce a color that is a mix of the two original colors, such as purple or magenta.
When you are painting, you would add white or another light color.
'Invert filter' in image processing is a technique that reverses the colors of an image. It changes dark areas to light and light areas to dark, creating a negative effect. This filter is often used for creative purposes or to enhance certain features in an image.
Use a light blue 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.
