When red light and green light shine on red curtains, the red curtains will appear red. This is because objects appear a certain color based on the wavelengths of light they reflect. Red objects reflect red light and absorb other colors, so even when green light is shone on them, they will still primarily reflect red light, maintaining their red appearance.

If the screen is actually white, it will absorb all light and appear black to your eye. If the screen appears white in normal light, all light will be reflected resulting in the combination of green and red (brown/yellow).
There are basically two different kinds of filters. The first kind belongs to the family of transition filters meaning that the only green light can come thought. The second one is absorption filter which passes everything though except the green light.
Green is not a primary color, it is a combination of yellow and blue.
To make green appear black, shine red light on it. Green absorbs red light, so when red light is shone on green, the green will appear black.
Things appear red because they absorb all wavelengths of visible light apart from red this will be reflected. If you only shine green light on the object it will all be absorbed and no light will be reflected so it will appear black.
When you shine a green light on a green object, the object will reflect the green light and appear brighter or more vivid in color. Green objects absorb most of the other colors of light and reflect green light, so they will be most visibly affected by green light.
When you shine yellow light onto a green surface, the surface will absorb the yellow light and reflect green light. This is because the surface appears green due to its ability to reflect green light while absorbing other colors.
When you mix red and blue, you get magenta. When you shine a green light on magenta, the green light will be absorbed by the magenta, resulting in a dark color or black, depending on the intensity of the green light.

When green and red light shine on a green leaf, the green light is mostly absorbed by chlorophyll for photosynthesis. The red light is less efficiently absorbed, so some is reflected back, leading to the leaf appearing green to our eyes.
If you shine a green light on a red cap, the cap will likely appear dark or black because red objects absorb green light and do not reflect it back to our eyes. This is due to the color mixing phenomenon where red and green cancel each other out.

Space is defined by its dimensions, properties, and contents. If its contents or properties (or even its dimensions) produce a purple colour on the application of light, either by scattering of red and blue frequencies, or by absorption of green, it could be considered 'purple space'. A room with purple wallpaper, for instance, is a space that is purple. Is the vacuum of outer space purple? Not really- it lacks colour generally until you shove something purple into it and shine a light upon it consisting of the requisite frequencies, or something white with purple light... or unless you can manipulate its properties to influence the frequency/absorption of light passing through it... or unless it has purple curtains...
