red filter.
A red filter blocks green light and blue light: Only red light can get through to your eyes.
What color does a green filter block?
Color filters block certain wavelengths of light and let others pass through. For example, a green filter blocks all wavelengths except green light. To create color pictures, a CCD takes three separate pictures of the same object using red, blue, and green filters.
Does a green filter absorb green light?
For instance, a green filter will absorb all wavelengths except for green light. In this sense, filters subtract colors from the mix of incident light, allowing only selected colors to pass through.
Is green light absorbed by the filter?
The filter selectively transmits the red and blue portions of the incident white light spectrum, but absorbs most of the green wavelengths. As discussed in our section on primary colors, the color magenta is obtained by subtracting green from white light.
What does a yellow green filter do?
The Cokin Yellow-Green filter is used primarily for black and white photography with a digital camera’s white balance set to black & white or for B&W film. The Yellow-Green is highly effective for outdoor portraits because red is rendered dark while yellows and greens appears lighter.

An ideal red filter transmits only red light and absorbs all other colors.Here, a magenta filter blocks green light and a cyan filter blocks red light (see below; click to enlarge). Only blue light can pass through to your eyes. The banana looks blue because the white fruit reflects some blue light.
What does a color filter do to light?

When you have a colored light and a filter that’s a different color What do you see?
If you pass white light through a red filter, then red light comes out the other side. This is because the red filter only allows red light through. The other colours (wavelengths) of the spectrum are absorbed. Similarly, a green filter only allows green light through.
What does blue look like through a green filter?
The problem is that the real filters are not perfect — the blue filter lets some red and green light leak through, and the green filter lets a lot of blue and some red leak through. So a yellow object, seen through the real blue filter, does not look black — it looks dull yellow.
What colour would blue jeans appear in green light?
The dye is intended to absorb all the colors of visible light except for blue. If only blue is reflected, then the jeans are “blue” jeans. 2. A red shirt looks red when visible light (“ROYGBIV”) shines upon it.

They can also be used in landscape photography to boost the appearance of grass and trees, but they also lighten the sky so you need to be careful not to lose detail there.
What color would the brain perceive green light to be through a red color filter?
yellow
For example, red and green lights are used to make our brain perceive the image as yellow. When coloured lights are mixed together, it is called additive mixing.
Does red cellophane block blue light?
That is why they look green! It’s because plants reflect green light and absorb the other colors. The cellophane you used blocks out the color of light that it appears to be, and lets the rest through. The red cellophane blocks out red light, and lets blue light through.
What color will objects appear if they are viewed through a green filter?
Objects seen through a green filter will look green if the objects absorb green light. Non-green objects will appear black because other wavelengths are absorbed by the filter.
What do different color filters do?
Coloured filters are exactly what they sound like; a piece of colored glass you place in front of the camera’s lens. These filters change how the camera sees the light, and the effect depends on the color of the filter. Blue filters will enhance reds and oranges, while playing up the contrast a bit.

The B+W 77mm UV Haze MRC 010M Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter.
