If red light passed through the filter, then it would not be a blue filter. When a broad range of colors encounters the blue filter, by far the greatest share of the light that comes out of the other side is blue light, with very small amounts of other colors.
A filter removes certain colors of light which pass through it. The primary colors of light are green red blue. Since the shirt absorbs all but blue light and the filter removes all but green it will appear black.
Red. A primary filter allows only one colour through.
In a real case the blue filter will pass a little red and the red filter would pass a little of blue, so you'd see a faint purple light.The blue filter will remove all the frequencies except blue. The red filter will remove all the colors except red. So it removes the blue, leaving nothing.Filters are seldom that good. Most filters have a curved response with maximum filtering at one color and less filtering on other colors.
After pure, white light passes through a red filter, all the other colors in the spectrum will flow out of the other side. My mistake, I had a faulty source. A red light filter will cause the image to appear as different shades of red. Since it is a red filter only red light can pass through. So you finish up with red light. Whether it is focussed to an image or not is of no consequence. As to different shades of red, you will get the shade of red that is passed by the filter.

the filter transmits red light and absorbs other colors.

Red.A red filter absorbs all light except for red light. Everything appears to be a shade of red.
All wavelengths of other colors of visible light are absorbed, only the wavelengths of red light will pass thru the glass.
Red or blue. The reason a red filter looks and is red, is because only red light comes through it, and the same can be said about a blue filter allowing only blue light through. Other colors are absorbed by the dyes in the filter. If white light enters a red filter, then red light comes out, and the same goes for blue.
An emitter of blue light shining on/through a red filter.The red filter appears red because it block all light except red. So trying to shine blue through it should attenuate the blue heavily. Only red can pass through the red filter easily.
No, the red absorbs all the colors in the light exceptred.
A green object appears black when viewed through a red filter (here a red filter means red light) because green object can only reflect green color and absorb all the other colors so in the red light it will definitely appear black.
