In red light a blue object appears black because there is no blue light for it to reflect, while black resembles the absence of all color.
A green object will appear dark or black under blue light because it does not reflect blue light well. Green objects absorb blue light, resulting in little to no reflection of this color.
A blue object would appear dark or almost black in magenta lights because magenta does not contain any blue light to reflect off the object, causing it to absorb most of the light.
In blue light, a yellow object would appear dark or black because yellow absorbs blue light and reflects other colors. This means that the object wouldn't reflect any of the blue light, making it appear dark.
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.
Red and blue are primary colours therefore they do not contain any other colour. When a blue light is shone onto a red object, all the blue light is absorbed by the red object, and as no red light is being shone for the red object to reflect, no light will be reflected from it and it will appear to be black. It is important to remember that physical colours will only reflect it's light colour equivalent. All other colours are absorbed. So red will reflect red, green will reflect green, and red will absorb green and so on.

A yellow filter would absorb blue light, making a blue object appear black in a black-and-white photograph.
it will look black but I am not sure
A green object will appear dark or black under blue light because it does not reflect blue light well. Green objects absorb blue light, resulting in little to no reflection of this color.
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.
A blue object would appear dark or almost black in magenta lights because magenta does not contain any blue light to reflect off the object, causing it to absorb most of the light.
It's called "A Blue Object" because when light of many colors falls on it, it reflects the blue light toward your eyes and absorbs all the other colors, including yellow. So if yellow light is the only light falling on it, the light is all absorbed, none is reflected to your eyes, and the object appears black.
In blue light, a yellow object would appear dark or black because yellow absorbs blue light and reflects other colors. This means that the object wouldn't reflect any of the blue light, making it appear dark.
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.
Blue appears black under a yellow light. For example if you have a blue car and you put a yellow light on it will appear black due to the absence of color. The light has nothing to reflect back.
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.
