Phosphorescent coating on the surface of the paper.
Paper will appear to be black under a red light because red light has a long wavelength and is less likely to reflect off the white surface of paper.
The can covered with black paper will heat up faster than the one covered with white paper. This is because black paper absorbs more light and heat energy compared to white paper, which reflects light.
The black ink absorbs most of the white light, reflecting very little back to our eyes. This absorption is what makes the ink appear black. The white paper reflects all colors of the white light, creating the contrast between the black ink and the paper.
The black paper will absorb more sunlight and heat up, causing the snow underneath to melt faster than the white paper. This will create a contrast where the snow under the black paper melts more quickly than under the white paper, showcasing the different heat absorption properties of the two colors.
If you put a piece of white paper under a green light all that will happen is the paper will turn green. The only time this will vary is if you have special ink that will show up under certain colored light.

Do a experiment on how black and white paper have different warmth under a light.

White paper burns faster than black paper because white paper reflects more light and heat energy, resulting in quicker ignition. Black paper absorbs more light and heat energy, which slows down the burning process.

White clothBlack paper absorbs more because black absorbs all colours of light and turns the light into heat.

When you place ice in a bowl with black paper underneath, the black surface absorbs more heat due to its color, causing the ice to melt faster compared to the bowl with white paper underneath. The white paper reflects light and heat, resulting in slower melting of the ice. This demonstrates the principles of heat absorption and reflection based on color.
If you are meaning black and white or colour films there has to be no light what so ever. Paper printing black and white prints can be done under safelight conditions, usually a deep yellow/orange safelight. Colour printing should be in total darkness. ordinary black & white? yellow or red panchromatic black & white? no light color? no light
White paper reflects more sunlight and heat compared to black paper, which absorbs more sunlight and heat. Therefore, black paper tends to get hotter faster and reach higher temperatures than white paper when exposed to sunlight.
