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.

Black
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.
Shadows appear black because they are formed when an object blocks light, preventing it from reaching the surface behind it. Since light cannot pass through the object, the area behind it appears dark in comparison to the surrounding illuminated areas.
A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can't reflect other colours, so it looks black. :)

It's one of the colour. Black colour absorb all colour. A perfect black body radiates heat.
Black is technically not a colour, merely an absence of colour. Light consists of seven colors, the object which will absorb all colors look black.

red filter

it should do objects absorb all light except light of the colour of the object if there is no light of that colour the object appears black
A red object looks black through a blue filter because the filter absorbs the red light that the object reflects, allowing little to no light to pass through. This results in the red object appearing dark or black when viewed through the blue filter.
