    HEXADECA-CHROMACY Pt. 2
    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.


    Reference: Color, is it in the brain?

    Imagine what other colors there could be.

    Things like this make me slightly emotional; the fact that I will never be able to experience all of these different colors that exist is pretty scary.

    Maybe you should look into LAB:

    'Unlike the RGB and CMYK color models, Lab color is designed to approximate human vision. It aspires to perceptual uniformity, and its L component closely matches human perception of lightness.' wiki

    Speaking of LAB, in a graphic design studio I worked at for about 4 years, we had a few of the Macs and printers set up to the LAB color system. Produced some wonky drop shadows.

    Has anybody heard of research linking females of species evolving to have 4 cones to see RGB and Y light? Definitely for other animals this is already a reality (bees is the first example off the top of my head) but what about Human females?

    Maybe in the digital age where we can reproduce the variety of colors in the color spectrum with advancing technology humans can evolve to have cones to see the other pieces or the entire spectrum of light.

    Agree, color research goes all the way from spectral phenomena through brain processing to verbalization by collective convention.

    I think that is what the author of the reference article means when he closes with " ... for the moment, I shall sit in the interactionist camp on this one!!!"
