the colors are mixing, and it should actually look purple, but appears to be black. (its like mixing paint in a way...)
When you look at a blue object through a red filter, the object will appear darker and possibly black because the red filter blocks out most of the blue light. The red filter only allows red light to pass through, which results in absorbed blue light and altered color perception.
A green object viewed through a blue filter would appear darker or black because the blue filter would absorb most of the green light, allowing very little to pass through. This lack of green light reaching our eyes makes the object appear darker and alters its color.
A blue object would appear darker when viewed through a green filter because the green filter would absorb some of the blue light that the object reflects, resulting in a more subdued color.
When you look through a red object, such as red cellophane or a red filter, the red object absorbs all other colors except red. This means that only red light is transmitted through the object. When you then view a blue object through the red filter, the blue object reflects blue light, but the red filter blocks it. As a result, only red light from the blue object is transmitted through the red filter, creating the appearance of purple.
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 yellow filter would absorb blue light, making a blue object appear black in a black-and-white photograph.
A red object would appear dark or black when viewed through a blue filter because blue filters absorb red light, preventing it from passing through. This would result in the red object appearing much darker since it is not reflecting or transmitting the blue light that the filter allows to pass.
A green object viewed through a blue filter would appear darker or black because the blue filter would absorb most of the green light, allowing very little to pass through. This lack of green light reaching our eyes makes the object appear darker and alters its color.

grey
You could use a yellow filter to absorb blue light, making the blue object appear black since no blue light would reflect off of it.
green
A blue object would appear darker when viewed through a green filter because the green filter would absorb some of the blue light that the object reflects, resulting in a more subdued color.
