Cryptochrome harnesses the energy of incoming blue light, but other molecules are probably needed to absorb light of other colors. — © Jeffrey C. Hall

There will be natural propriety in using an eastern light for bedrooms and libraries, a western light in winter for baths and winter apartments, and a northern light for picture galleries and other places in which a steady light is needed; for that quarter of the sky grows neither light nor dark with the course of the sun, but remains steady and unshifting all day long.
Each band or level, being a particular manifestation of the spectrum, is what it is only by virtue of the other bands. The color blue is no less beautiful because it exists along side the other colors of a rainbow, and "blueness" itself depends upon the existence of the other colors, for if there were no color but blue, we would never be able to see it.
Rays were blazing through the atmosphere of the earth, the horizon became bright orange, gradually passing into all the colors of the rainbow: from light blue to dark blue, to violet and then to black. What an indescribable gamut of colors! Just like the paintings of the artist Nicholas Roerich.
The brightest light, the light of Italy, the purest sky of Scandinavia in the month of June is only a half-light when one compares it to the light of childhood. Even the nights were blue.
I use colors that have already been experienced through the light of day and through the state of mind of the total man. In other words, my colors are not colors that are laboratory tools which are isolated from all accidentals or impurities so that they have a specified identity or purity.
Light in the heart has an interesting phenomenon. When you look at this world from here, now, light has shadows because light comes from a source. But, the same light inside the heart, which I've spent so much time looking at and so have other people, has no shadow because the light appears to come from everywhere.
Cause I am strong and I can prove it And I got my dreams to see me through It's just a mountain, I can move it And with faith enough there's nothing I can't do And I can see the light of a clear blue morning And I can see the light of brand new day I can see the light of a clear blue morning And everything's gonna be all right It's gonna be okay [lyrics from "Light of a Clear Blue Morning"]
All great films are a resolution of a conflict between darkness and light. There is no single right way to express yourself. There are infinite possibilities for the use of light with shadows and colors. The decisions you make about composition, movement and the countless combinations of these and other variables is what makes it an art.
We know what molecules are needed to sense light - what turns that signal that detects light into an electrical signal. We know how smells are detected. But we have a vast number of senses for which we know what the signal is, but we don't know what the receiver is.
Darkness is drawn to light, but light does not know it; light must absorb the darkness and therefore meet its own extinguishment.
Greek architecture taught me that the column is where the light is not, and the space between is where the light is. It is a matter of no-light, light, no-light, light. A column and a column brings light between them. To make a column which grows out of the wall and which makes its own rhythm of no-light, light, no-light, light: that is the marvel of the artist.
The light is there, and colors surround us. However, if there were no light nor colors in our own eye, we wouldn't perceive such things outside of us.
The scale of light can be described by numbers called the frequency and as the numbers get higher, the light goes from red to blue to ultraviolet. We can't see ultraviolet light, but it can affect photographic plates. It's still light only the number is different.
It is sometimes said that scientists are unromantic, that their passion to figure out robs the world of beauty and mystery. But is it not stirring to understand how the world actually works — that white light is made of colors, that color is the way we perceive the wavelengths of light, that transparent air reflects light, that in so doing it discriminates among the waves, and that the sky is blue for the same reason that the sunset is red? It does no harm to the romance of the sunset to know a little bit about it.
I always wanted to make a light that looks like the light you see in your dream. Because the way that light infuses the dream, the way the atmosphere is colored, the way light rains off people with auras and things like that...We don't normally see light like that. But we all know it. So this is no unfamiliar territory - or not unfamiliar light. I like to have this kind of light that reminds us of this other place we know.
In thinking of light, if we can think about what it can do, and what it is, by thinking about itself, not about what we wanted it to do for other things, because again we've used light as people might be used, in the sense that we use it to light paintings. We use it to light so that we can read. We don't really pay much attention to the light itself. And so turning that and letting light and sound speak for itself is that you figure out these different relationships and rules.
