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.
Filter is fixed on the head of flashlight to change light color. If you use red filter, the beam will be in red light.
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".
If the filter is magenta that is the combination of red and blue. They are the addictive primary colours, so a magenta filter blocks green light. hope this helped

All bacteria, including cocci, are colorless under the microscope unless you use a light filter or a stain. If you use a light filter or a stain then the color depends on which wavelength the filter is for or which type of stain you are using.

When you are painting, you would add white or another light color.
