Eric Rohmer on the use of Colour in "La Collectionneuse" (1967) and "Claire's Knee" (1970): "I didn't use color as a dramatic element, as some filmmakers have done. For me it's something inherent in the film as a whole. I think that in 'La Collectionneuse' (1967) color above all heightens the sense of reality and increases the immediacy of the settings. In this film color acts in an indirect way; it's not direct and there aren't any color effects, as there are for example in Bergman's most recent film, his second one in color, where the color is very deliberately worked out and he gets his effects mainly by the way he uses red. I've never tried for dramatic effects of this kind, but. for example, the sense of time-evening, morning, and so on-can be rendered in a much more precise way through color. Color can also give a stronger sense of warmth, of heat, for when the film is in black-and-white you get less of a feeling of the different moments of the day, and there is less of what you might call a tactile impression about it. In 'Claire's Knee' (1970), I think it works in the same way: the presence of the lake and the mountains is stronger in color than in black-and-white. It's a film I couldn't imagine in black-and-white. The color green seems to me essential in that film, I couldn't imagine it without the green in it. And the blue too-the cold color as a whole. This film mould have no value for me in black-and-white. It's a very difficult thing to explain. It's more a feeling I have that can't be reasoned out logically." (Eric Rohmer's interview with Graham Petrie, Film Quarterly, 1971)

Anna's Hummingbirds have been fooling humans for centuries with red throats. Those blazing crimson feathers that catch sunlight and seem to glow from within contain zero red pigment. The bird's gorget is built from microscopic transparent platelets stacked like glass slides, each one precisely 400 nanometers thick. When white light hits this biological interference filter, most wavelengths cancel each other out through destructive interference. Only red light at 630 nanometers survives the gauntlet and bounces back to your eye. The bird is essentially wearing a living hologram. Move your head three degrees to the left and the red vanishes completely. The angle change shifts which wavelength survives the interference pattern. The throat flickers between crimson, orange, deep purple, and invisible black as the bird moves through space. Every hummingbird species fine tuned their microscopic architecture to reflect different wavelength combinations. Anna's chose red. Allen's chose orange. Broad-tailed chose magenta. Each species evolved their own optical signature by growing feather structures at slightly different nanoscale dimensions. The precision required borders on impossible. These birds grow biological optical computers on their bodies. Each platelet must be manufactured to within a few nanometers of the target thickness or the color shifts completely. Human engineers struggle to build interference filters this precise in clean rooms with million dollar equipment. A hummingbird grows them while hanging upside down drinking sugar water. The evolutionary implications are staggering. Female hummingbirds are literally selecting mates based on their ability to grow functional nanophotonic devices. Males with better optical engineering get to reproduce. Sexual selection drove these birds to become living examples of advanced materials science. Your eye processes the reflected light as "red" but the bird's throat contains nothing red at all. The color exists purely in the interference between transparent surfaces and incoming photons. The hummingbird bent light itself into love.
