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.
