What color absorbs heat the slowest?
The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
Light colored clothing reflects most of the visible wavelengths which, in turn, absorbs less heat. On the contrary, darker or black clothing absorbs more wavelengths, absorbing more heat, hence making the clothing warmer to wear.
White is a bad absorber of light because it reflects all colors, not taking in any light energy. It only reflects the color waves, meaning that it's not absorbing much heat, and therefore that makes it the coolest color.
The only color that does not attract heat is white because white objects reflect all visible wavelengths of light. Black – the color that absorbs all visible wavelengths of light – attracts the most heat, followed by violet, indigo, blue, green, yellow, orange and red, in descending order.
Dark-colored materials absorb visible light better than light-colored materials. That's why the dark side of the card heats up first. The lighter side absorbs less of the incident light, reflecting some of the energy. Darker materials also emit radiation more readily than light-colored materials, so they cool faster.
Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up. Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top.
1. Wear White. A white object is white because it reflects white light, and white light is a combination of all the visible colors. This means that a white shirt (or pants) will reflect most of the light and not get hot.
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.
Teal, green and blue-green colors reflect heat and create a cooler feeling than other color hues. Pale yellow also cools the home. Yellow, like light gray, reflects 90 to 95 percent of available light and heat.
Red is the lowest energy visible light and violet is the highest.
What color least attracts the sun?
Darker colors absorb more UV than lighter colors like whites and pastels. This means the UV rays are less likely to reach your skin. But bright colors such as red can also absorb UV rays.
Darker colors absorb more sunlight than lighter colors, which is why darker colors get warmer more quickly in the sunlight than lighter colors. The lighter colors reflect more of the sun's radiant energy, so they remain cooler to touch in the sunlight.

After white, the colours that keep the body cool are none other than yellow, grey, and — surprise — red, still considered in the collective imagination as a 'warm' colour. Purple is in the middle of the ranking, so it can be worn during hot weather if it is your favourite colour.
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.
Red has the longest wavelength of visible light, so it has the lowest energy. Violet light has the shortest wavelength, and so it has the highest level of energy of visible light.
The answer to this one is a little surprising. White (or transparent) is the colour that holds heat longest!
