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.
White paper appears to glow under a black light because the phosphors in the paper fluoresce when exposed to the ultraviolet light emitted by the black light. This causes the paper to emit visible light, creating the glowing effect.
The light is absorbed by the black ink and reflected by the white paper surrounding the ink. That is why you can see the ink clearly.
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.

they both look white
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.
Anything perfectly black appears black because it absorbs all the colors of the visible spectrum instead of reflecting them like white paper, so the light energy is absorbed and transfered into heat energy (the paper warms up very slightly).
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.
