### Why do lighter colours reflect the heat instead of absorbing the heat?

It's not the fact that lighter colours reflect the heat as much as it is the fact that they reflect the light. Light colours mean that more of the light is reflected off them (otherwise we would have no differing colours - it would all be black), while darker clothing absorbs the light. When the light is absorbed, the laws of thermodynamics state that the energy has to go somewhere. It turns into heat. If you were standing in a completely dark room with a set temperature, it would not matter what colour your clothes were, as there would be no light that could turn into heat.

### Do Lighter color surfaces reflect more or less energy than darker colored ones?

Light is energy. More light is reflected by light coloured surfaces. Therefore...

### How does paint affect the temperature on surfaces?

Lighter colors reflect light, darker colors absorbs more light which makes the surface warmer.

### How do you know that most objects reflect more than on colour of light?

You can diffract the light reflect from the object and see what range of spectrum is absorbed and what is reflected. It is to mentioned, human had trichromatic vision. We base our vision of colour from the portion of red blue and green. The real colour in spectrum is however continue of colour from red to violet. By having only 1 colour of light reflect, the object had to specifically absorb exact the other 2 portion of light human can see which is extremely rare for natural objects without specific design to absorb light at exactly cover the other 2 spectrum human can see. So it is most objects would reflect more than one colour of light.

### Why do light coloured objects reflect radiation more than dark coloured objects?

Because dark colours absorbs light, and energy;and its named absortion coefficient. ============================== Some substances and objects made from them reflect more light and absorb less. Other substances and objects made from them reflect less light and absorb more. The ones that reflect more and absorb less are the ones that appear lighter to us. Why ? Because they absorb less light and reflect more of it toward our eyes.

### Why does paper reflect light?

White reflects more light than any other colour, while black absorbs more light than any other color. To get technical, photons that are not absorbed by the paper will bounce off (be reflected by) the paper and make it appear lighter or white. Short answer: because most paper is white.

### Why do darker surfaces heat up more than lighter ones when light hits them?

Dark colors absorb light creating thermal energy. Light colors reflect more light and heat away.

### What colour absorbs the most light?

A black non-shiny surface will capture more light. It is also the kind of surface which does not reflect the light which it has caught. Such a surface is also excellent at absorbing heat. It is the lighter colours and the shinier surfaces which reflect light. This makes one wonder why women in some hot countries, such as those in the northern parts of Africa wear black material which almost covers all of their body's surface.

### What colour car absorbs more heat black red blue green whiteshinyb or dull surface?

black, because darker colours absorb more heat than lighter colours. I'd say that dull colours absorb more heat, as shiny colours reflect more heat and light.

### How does the colour of light affect plant growth?

Plants are green because the reflect green light. They do not use green light, they use red light to make food. Some plastic mulches are red to reflect red light onto plants to make them grow more.

### Why does a darker color absorb more heat than a lighter color?

Dark colours do not exactly absorb more heat, but they do convert a higher percentage of light into heat. If you notice when heading out in the sun with a dark coloured shirt it gets hot, where a lighter coloured shirt would not get nearly as hot. This is due to the amount of light being absorbed by the colour. The lighter the colour the smaller the range of visible light being absorbed and converted into heat. White objects reflect all visible light, where black objects absorb all visible light. This is also why we call both dark coloured objects and poorly lit objects dark. While colour is a factor of light absorption, it is not the only factor. You will find that some dark objects remain cooler in direct sunlight then other lighter objects. This is due to the fact that there are other factors at play, maybe one material is a poorer insulator; possibly there is a shine to darker object, leading more light to be reflected as a result. But if all but the colour is the same, you will find that darker colours do become hotter when exposed to light.

### Why do dark colors attract more light and heat than light colors?

They do not attract light, they absorb it, that is why they are darker. Light colors reflect more light (to your eyes), that is why they are light. it has to do with the light energy that doesn't stop, lighter colors tend to reflect when there isn't a place for the light to bounce off of it has to stop and the energy remains as heat because dark traps the light and doesn`t let go
