Because the material it is made out of only reflects white light.
A combination of red, green, and blue light on a white sheet of paper would create white light. This is because white light is produced when all three primary colors of light are combined in equal intensities.
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.
A black sheet of paper has the lowest albedo among the options given. Albedo refers to how much light a surface reflects, and black surfaces absorb more light, reflecting less back. The white sheet of paper would have a higher albedo due to its ability to reflect more light.
Any light that does not contain the primary color red will make the sheet of paper look black. (for example green, blue, cyan,... but not yellow, violet,...) This is because the surface of the sheet is such that it absorbs all the colors of white light except red which is reflected and which is why it appears red in white light.
Red. As the filter will only allow red light through, it, you can not see anything but reds.
it is white sheet

they both look white
will appear black

accounts paper's
My answer for that is Yes or No.(Yes because,some sheets are white just like a sheet of a paper.)(No because,some other sheets are not white.So it can't be used in the simile "as white as a sheet".)
As white as a freshly fallen snow. White like a pearl shining in the sun. White as a blank sheet of paper.
Red. As the filter will only allow red light through, it, you can not see anything but reds.
