When white light falls on an object the body absorbs all colors of light and reflects some colors of light which we see the object to be. A red ball reflects red color and absorbs the rest colors.So,if I throw green light on a red ball the ball will absorb that green light.
When light hits a surface, some of it is absorbed and some of it is reflected. For example, a green object appears black in any other light than green (or white which contains green) because there is no green light shining on it to reflect into your eyes.
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.
A red pigment is capable of absorbing cyan light. That is, red paper can absorb both green and blue primary colors of light (recall that cyan light is a mixture of green and blue light).
Each beam of light, with its own particular wavelength (or color), is slowed differently by the glass. Since violet light has a shorter wavelength, it is slowed more than the longer wavelengths of red light. Consequently, violet light is bent the most while red light is bent the least.
If you pass white light through a red filter, then red light comes out the other side. This is because the red filter only allows red light through. The other colours (wavelengths) of the spectrum are absorbed. Similarly, a green filter only allows green light through.
So shining red light on a blue object would, in an ideal world, show it as black. In the real world no object is perfectly blue, it will reflect some light outside the blue.
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.
As a result, the flower absorbs 100% of the light shone on it, reflecting no light and therefore appearing black (the "color" that results from the absence of light).
The Purkinje effect (sometimes called the Purkinje shift) is the tendency for the peak luminance sensitivity of the eye to shift toward the blue end of the color spectrum at low illumination levels as part of dark adaptation. In consequence, reds will appear darker relative to other colors as light levels decrease.
(See Diagram A) These three resulting colors, cyan, magenta and yellow, are the three primary colors of pigment. These are the purest colors, and cannot be produced by mixing other pigment colors. Using these three colors, you can produce a vast number of other colors.
When the red cellophane, a transparent material, covers the flashlight the light from the flashlight appears red because the cellophane absorbs all wavelengths of white light that comes from the flashlight except for the red wavelength. This wavelength is transmitted through the cellophane making the light appear red.
If you mix red, green, and blue light, you get white light.Mixing the colors generates new colors, as shown on the color wheel or circle on the right. This is additive color. As more colors are added, the result becomes lighter, heading towards white.
primary colours of lightGreen (1), blue (2), and red (3) are the primary colors of light. A mixture of two primary colors of light can make cyan (4), yellow (5), or magenta (6).

So, what colors make a room look bigger? For an optimum effect, go with soft tones like off-white, blues, and greens, and always remember that brighter rooms feel bigger and more inviting. And here's another hack: Try painting your wall trim and moldings in a lighter color than your walls.
A red colour paint is used to prevent the silver coating on the mirror from getting scratched.
Primary ColoursA green object appears black under red light. A red object appears black under blue light. A blue object appears blue under blue light.
When a color (colored fabric) absorbs light, it turns the light into thermal energy (heat). The more light a color absorbs, the more thermal energy it produces. Black fabric absorbs all colors of light and is therefore warmer than white fabric which reflects all colors.
Does Gray Absorb Heat? Colors absorb heat because of how they absorb light. Black will absorb more light from the sun, which means absorbing more heat, while white reflects more light, meaning it absorbs less energy and heat from the sun.
As a perfect mirror reflects back all the colours comprising white light, it's also white. That said, real mirrors aren't perfect, and their surface atoms give any reflection a very slight green tinge, as the atoms in the glass reflect back green light more strongly than any other colour.
