What doesn't transmit light creates its own darkness.
Black is not a color.
There is only one fault, only one: our inability to feed upon light.
When the light returns to its source, it takes nothing of what it has illuminated.
There is no greater mystery to me than that of light traveling through darkness.
I like to describe my life as a black hole with a little light out there.
By the way, most of the light that comes from the sun is green.
Nature has put itself the problem how to catch in flight light streaming to the earth and to store the most elusive of all powers in rigid form. To achieve this aim, it has covered the crust of earth with organisms which in their life processes absorb the light of the sun and use this power to produce a continuously accumulating chemical difference. ... The plants take in one form of power, light; and produce another power, chemical difference.
To any white body receiving the light from the sun, or the air, the shadows will be of a bluish cast.
Research is a scientific activity dedicated to discovering what makes grass green.
We learn that it is not the rays which bodies absorb, but those which they reject, that give them the colours they are known by; and in the same way people are specialized by their dislikes and antagonisms, whilst their goodwill is looked upon as no attribute at all.
The more an object is polished or brilliant, the less you see its own color and the more it becomes a mirror reflecting the color of its surroundings.
There are chemists who spend their whole lives trying to find out what's in a lump of sugar. I want to know one thing. What is color?
Green, red, and mixed shades of haemins are known. If magnesium is replaced by iron in chlorophyll, green haemins are obtained. Their colour is due to a strong band in the red which is already recognized in chlorophyll.
Curiously, light-loving green plants reject the Sun's green light, reflecting it back at you, which is why they look green.
It's not very fun to do spectroscopy.
The blackest of fluid is used as an agent to enlighten the world.
Whiteness is the color of death, you know, not black. Wetness is life, the breeder and shaper of life. In the beginning the sun was black. So all light was absorbed before it had a chance to return. And our dreams, then, were empty.
Light refused increases darkness.
Cryptochrome harnesses the energy of incoming blue light, but other molecules are probably needed to absorb light of other colors.
When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do some kind of dance, the net result of which is the same as if the photon hit only on the surface.
I am struck by the simplicity of light in the atmosphere in the autumn, as if the earth absorbed none, and out of this profusion of dazzling light came the autumnal tints.
There are many unidentified bands in the spectra of stars. Wide bands are produced by some complex molecules in the interstellar space.
Some people reflect light, some deflect it, you by some miracle, seem to collect it.
Yes, instruction! Light! Light! Everything comes from light, and to everything it returns.
