Farbwahrnehmung
Bereits 1856 gab Maxwell folgenden grundlegenden Ratschlag zur
Untersuchung der Farbwahrnehmung:
When a beam of light falls on the human eye, certain sensations
are produced, from which the possessor of that organ judges of
the color and luminance of the light. Now, though everyone experiences
these sensations and though they are the foundation of all the
phenomena of sight, yet, on account of their absolute simplicity,
they are incapable of analysis, and can never become in themselves
objects of thought. If we attempt to discover them, we must do
so by artificial means and our reasonings on them must be guided
by some theory. (Maxwell, 1856/1970, S. 62)
Diese Aufforderung soll der hier zu beschreibenden Untersuchung
zugrunde liegen; zunächst sollen deshalb die theoretischen
Grundlagen der Farbwahrnehmung dargestellt werden. |
