You will get Cyan (light blue)
Light blue
dark blue, maybe or light blue too
It would still look blue :)
Magenta.
Nothing comes through. A red light emits no blue light, and a blue filter allows only blue light to pass ... that's why when you look at it, you say to yourself "Hey! That filter looks blue. I'll call it a 'blue filter'."
you stupid colour blind its purple man
black because blue light cannot pass through a yellow filter
You can't see it because a blue filter only lets blue light in, and red is made up of just red light, no blue, so none passes through (or it gets reflected, can't remember which)
blue
Blue is a primary light colour so it exists all the time. You cannot make it from any other colour. Shine a bright white light through a prism or look at a rainbow, you can see the "blue" part of the visible spectrum. Shine a light through a "blue" filter you can see the blue colour on a substrate. Between 400 and 500 nano meters frequency is where blue can be found

I think you would see blue.I say that, because I'm thinking to myself: "WHAT MAKES THE FILTER BLUE ? ! ? !"
A red filter will absorb all but the red wavelength of light. A blue filter absorbs all but blue light. So the blue filter will absorb the red wavelength and no light will shine through.
A cyan colored surface will reflect any blue or green light that is incident. The green filter will remove all colors of light passing through it except green. The book is illuminated with only blue light. Draw your conclusion.
Shining a blue light through a cyan filter will result in a blue light shining through. As cyan is a combination of blue and green light, it will allow blue and green light to pass through it. Red light will be absorbed by the filter. This is proven by shining a violet or magenta light through the filter and it allowing blue light will shine through. It is shown as well by shining a yellow light through the filter which will result in green light shining through as both violet and yellow are a combination of red the other two primary colours, blue and green.
Blue light will simply pass through a blue filter, as the filter will only absorb colours which are not blue (red and green).
