    Why is the sky blue? The simple answer is Raleigh Scattering. But it is not until it reaches the observer, specifically the brain, that the wavelength is interpreted as "blue". It is easy to detatch the concept of color from the eyes once you understand that there is nothing physically inherent about color.

    We try to reproduce the wavelengths of light that correspond to our vision on computers through color systems. These color systems are not derived empirically, limiting the colors displayable by a CPU to those describable by the system. The color system also assumes that our eyes have equal sensitivy to color, when in actuacility there are far fewer receptors on the blue end of the spectrum and what we consider the “red” in RGB is actually a yellow-green.

    The hexadecimal color coordinate system uses 16 distinct symbols, most commonly the numbers 0 - 9 and the letters A - F. The color coordinate system uses the naming convention #RRGGBB with two symbols representing each primary color coordinate.

    Colors are a strangely elusive concept; they seem so arbitrary. Shapes, lightness, tone seem far less arbitrary than colors. Either something is giving off / reflecting light, or it's not. But color is different. Even now, scientists cannot define the attributes of color or understrand the processes of concious perception color.

    Mankind evolved on the grasslands of Africa; our vision limited only by the horizon and the mountains. Color is intimately intwined with human perception, but in the end it may very well be a purely Earthbound idea.

    From the perspective of the floating head, vision is the most direct and descriptive form of interaction we have with the universe. We can interpret textures, colors, brightness, darkness, shapes, etc. through sight alone. We are a highly visual species. The occipital lobe, although the smallest of the four paired lobes, is the most dedicated. Its two functions are to interpret visual information and to dream. In our endeavors towards a stellar civilization, the limits of our vision are often overlooked in arrogance.

    The cosmos for instance is something we can only engage in visually. Not being physically capable or on the scale to experience it otherwise we rely on visual interpretation to understand the physical object.

    (sounds of the universe)

    Imagine alien visitors who have evolved around a different sun landing on Earth only to find their "color" vision, comprised of primary colors elsewhere on the electromagnetic spectrum, is incompatible with human communication.

    Our trichromatic vision evolved as a way of differentiating between the wavelengths of light most useful to us. Likewise, animals have evolved color vision most effective to their survival, some resulting in tetrachromatic vision.

    (tetrachromacy in humans)

    The only way for trichromatic humans to visualize multi-chromacy beyond the third degree is through projected representations on to the rgb spectrum.

    There are ideas only describable through vision; something inherently romantic about sight. The notion of image allows us to experience, learn and interpret objects and scenarios (real or hyper-real) that are not immediately within our grasps. It seems, though we think in words, we dream in pictures.
