red filter
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'."
Since the filter allows only blue light to pass through, anything you see through the filter appears either blue or black. Blue if there's any blue light coming from it, or black if there isn't any.
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.
