A Green object will ABSORB its complement (Magenta = Red + Blue). So, since Red light is ABSORBED by the Green pigmented object, NO LIGHT reflects back to your eyes, thus you “see”
black
.
What happens if you put red light on a green object?
When we look at an object and see its color, we are seeing all of the light that reflects off of that object. Red objects reflect red light, green objects reflect green light, and so on. But what happens to the rest of the colors that hit that object?
They get absorbed
!
What colour would a green object appear in red light?
Primary Colours
A green object appears
black under red
light. A red object appears black under blue light. A blue object appears blue under blue light.
Does green absorb red light?
Chlorophyll, the pigment that makes plants green,
absorbs light in the red end of the spectrum
and light in the blue end of the spectrum. A green leaf is green to us because the middle band of visible light is not absorbed and is instead reflected into our eyes.
Why does a green object look black in red light?
The observer sees the object as the colour green. In diagram 2, the same object is seen under red light. Because
the green surface absorbs all colours other than green, no light at all is reflected from the object
. No light enters the observers eye, so the object appears a black colour.
What colour does a yellow object appear in red light?
Because yellow light is a mixture of red and green light, yellow will also reflect red and green light. This means that a yellow object will appear
red under red light
, and green under green light.
What Colour light does a green object absorb?
Pure green pigments absorb
magenta light
(which can be thought of as a combination of red and blue light). Pure magenta pigments absorb green light. Pure red pigments absorb cyan light (which can be thought of as a combination of blue and green light).
What color does red and green make?
When the red and green lights mix, the result is
yellow
.
What Colour does blue appear in red light?
If only blue light is shone onto a red shirt, the shirt would appear
black
, because the blue would be absorbed and there would be no red light to be reflected. White objects appear white because they reflect all colours.
Why is green the worst color for photosynthesis?
Green is
the least effective color of light in driving photosynthesis
, the process of converting light energy into chemical energy. Photosynthesis occurs in plants and algae using chlorophyll, and because chlorophyll reflects rather than absorbs green light, green light cannot be used in the photosynthetic process.
What colors absorb what colors?
| Color absorbed Color seen | Blue Orange | Green Red | Yellow Violet | Orange Blue |
|---|
What color light do you add to red to produce white light?
If you mix
red, green, and blue light
, you get white light.
Red, green, and blue (RGB) are referred to as the primary colors of light. Mixing the colors generates new colors, as shown on the color wheel or circle on the right. This is additive color.
Why is red light used in traffic lights as a signal to stop?
As we know red light is used to stop vehicles. The reason behind is red light is having longer wavelength. … Therefore the red light can travel the longest distance through any fine particle. Hence in traffic signals red color light is used to stop vehicles because
it is having the highest wavelength
.
Is black a colour?
Black is the absence of light
. … Some consider white to be a colour, because white light comprises all hues on the visible light spectrum. And many do consider black to be a colour, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colours, they’re shades.
What colors show up in red light?
Any color which reflects red will
appear “white”
, i.e. white, red, orange, yellow. Any color which absorbs red will appear “black”, i.e. green, blue, black. Colors that reflect some red appear gray, i.e. purples and some browns.
What colors show up under red light?
Any color which reflects red will appear “
white”
, i.e. white, red, orange, yellow. Any color which absorbs red will appear “black”, i.e. green, blue, black.
