The color white reflects sunlight best because white does not absorb any light that hits it, instead reflecting it all back.

What color paint reflects the most sunlight?
ultra-white
Tests carried out by researchers at Purdue University on their “ultra-white” paint showed it reflected more than 98% of sunlight. That suggests, the scientists say, that it could help save energy and fight climate change.
What is the most heat reflective color?
White and Black
White objects reflect all visible wavelengths of light, while black objects absorb all visible wavelengths. As a result, these two colors attract the least and the most heat, respectively.
What color reflects heat and sunlight best?
white
For exterior paint to keep your house cool, white is a popular choice. It brightens the look of your home and reflects light, and therefore heat, from the sun.
What reflects sunlight the most?
Conversely, light colors reflect more light than dark ones, and white reflects the most.
What is the most reflective paint?
Germicide Reflective Paint – Lumacept Max provides the most reflectivity out of any other paint. It offers 10x the reflective power of regular paint. This paint is best people who would like the most thorough disinfection due to the presence of immunocompromised people or animals.
What color is an object that reflects all light?
White objects
White objects look white because they reflect back all the visible wavelengths of light that shine on them – so the light still looks white to us.
Is it better to wear white or black in the sun?
They both reflect about the same amount of thermal radiation. That means you are going to be better off with white clothes, since they don’t absorb as much visible light.
What color keeps you cool in the sun?
White
White, yellow, gray, and red
It is commonly said that white is the most appropriate colour for summer temperatures because it keeps the body cool, unlike black which tends to absorb heat.
What color is coolest in the sun?
White, silver, and other light colors are coolest, reflecting about 60 percent of sunlight but there are dark “cool” colors that can also stay cooler than traditional dark colors.
Is it better to wear black or white in the heat?
Black does absorb heat from the sun at a faster pace than white, but black also absorbs the heat from your body as well. Throw a little wind into the mix and black is the better choice for wicking away the heat away from your core. There are some interesting articles that go into more explanation.
Does blue reflect sunlight?
If an object is not totally transparent or reflective, then it is capable of absorbing energy in the form of light or heat. If something is blue, that means it absorbs all frequencies of visible light except blue (450 nanometer wavelength) light which is reflected or transmitted through.
Does GREY reflect heat?
Anything that reflects a color will look that color.
White, gray, and black are not colors, though: white reflects all colors, black absorbs all colors, and gray reflects some and absorbs some of all colors. Light is energy. Any light that is absorbed, of any color, becomes heat.
Does green reflect sunlight?
In conclusion, plant leaves are green because green light is less efficiently absorbed by chlorophylls a and b than red or blue light, and therefore green light has a higher probability to become diffusely reflected from cell walls than red or blue light. Chlorophylls do not reflect light.
Which reflects more sunlight back?
A perfectly white surface has an albedo of 1.0 (all radiation is reflected). Snow and ice have high albedo – much of the sunlight hitting surfaces covered with snow and ice bounces back. In contrast, dark earthy surfaces have a low albedo, therefore, they absorb more sunlight.
Does the color red reflect sunlight?
Colour of objects
The colours we see are the wavelengths that are reflected or transmitted. For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum. Red light is the only light that is reflected from the shirt.
What kind of paint is reflective?
Reflective paint is regular paint with a tiny additive that makes all the luminous difference. Small reflective crystals are added to a gallon of flat, satin or eggshell paint either at the factory or at home.
What is the most reflective white?
According to research led by Purdue University professor Xiulin Ruan and published in the journal Cell Reports Physical Science, the new “whitest white” is capable of reflecting about 95.5% of ultraviolet light that hits it.
Is white or silver more reflective?
Silver reflects much more light, so you’ll use silver when you position the reflector back away from your subject. If you need to get a reflector right up close, then use white, because it doesn’t reflect nearly as much light as silver.
Does white colors reflect sunlight?
White surfaces can reflect a considerable amount of light, but without the mobile electrons to oppose the electric field of light, white surfaces allow light to penetrate up to several wavelengths.
What color absorbs the most light besides black?
Obviously the black strip absorbed the most. But the red, blue, and green ones did not absorb much. Interestingly, the dark gray and purple ones absorbed absorbed more than I would imagine.
