How much light does the color black absorb?
July 16, 2015 2:26PM
Colors absorb the light that the color is and reflects the rest so with black most.On the color spectrum, white is the absence of all color, black is the result of all color. The reason the black interior of your car gets very hot in the sun is that it absorbs the whole spectrum.
What model of color mixing creates black?
We normally think of Black as a color, but we need to understand that Black is no color at all. Black is instead absense of color, or rather absense of light. When you turn off all light in a dark room, then you see nothing. You have successfully "created" black. As for "black" objects we see, this is another aspect of exactly the same thing. The black object simply does not reflect enough light for us to distinguish it as anything but black, or lack of light. In other words, the black objects absorb as much as possible of the light shining on them.

How will a green plant grow with green light?
Because the plant is green, we know that its main color receptors are chlorophyll a and b. These absorb mostly red and blue light, and absorb green the least. If only exposed to green light, the plant will not grow as much as if it were exposed to a full spectrum of colors, or as much as if it were exposed to red or blue light.

What color is outer space?
What paint color will make a difference to the temperature in a pool?
As a general rule, darker colors will absorb more sunlight (thereby converting it to heat) than light colors. Black will, of course, absorb the most. Brown or deep blue will be close behind, but not because of what the hue is, just because those can be made in very dark versions that don't reflect much light.
Why does the colour of something affect the amount of heat it gains?
Because the colour of something affect the amount of heat absorption by radiation. Black bodies absorb the most radiation while white bodies absorb the least radiation. (reflecting heat radiation) Answer 2: The color of an object depends on what color of light it reflects back. A red object absorbs all other colors and reflects red light to your eyes. White is all colors and black is no light. You've probably heard wearing black in the sun makes you very hot. This is because there is no light being reflected back, it's all absorbed. A white shirt is cooler because it reflects all light colors and absorbs much less. Now, what determines the color that is reflected is the atomic composition of the object. Different colors of light have different frequencies, and certain atoms and materials absorb only certain frequencies of electromagnetic radiation (light). So it's not really the color that determines the amount of heat absorbed, it is the composition of the material that determines both the colors of light that are absorbed and thus, how much energy is absorbed. The color is a secondary effect perceived by you, it really doesn't control the heat absorption, it's a result of the atomic structure of the material.
Asked in Energy
Will a dark colored liquid heat faster than a lighter colored liqui?
YES!!!!! This happens because different colors absorb different wavelengths of light. As you can see with a prism, white light is actually made up of all the other colors. When this white light hits an object, some of the wavelengths that make up the light will be absorbed by the object, and the rest will be reflected. A red apple looks red to us because it reflects the red light wavelengths and absorbs every other color. Black substances don't reflect any wavelengths, so they absorb the most light, and in turn the most heat. However, white substances reflect all wavelengths, so they don't absorb much light or heat, and they are cooler. So while a white liquid would absorb some heat, a black liquid would heat up at a much faster rate, and the dark liquid would be hotter.

Asked in Physics, Chemistry, Science Experiments
Why does red absorb more light than blue?
It doesn't quite work that way. Red objects absorb more of any light that is not red (red is mainly reflected, that's why we see it red). Blue objects absorb more of any light that is not blue. So, how much total energy is absorbed will depend on the specific color (what type of red? what type of blue?) as well as on the specific mix of frequencies of the light.

How do you make black color?
Black is the total absorption of incident light. You can do this making a big molecule which can absorb all EM radiation between 400 and 700nm or using a bland of cyan, magenta and yellow colours. Added: This can be done much easier by adding sufficient fine powdered amorphous carbon (called 'carbon black') to the colorant or paint.
