This gallery can be viewed as a sort of "color study". Compared to other material on the site, it is more educational and concerned with describing technique more than finished work. From the computational viewpoint RGB color space is just a 3-dimensional space. Colors are points in this space and color sequences are paths or orbits through the space. By my preference, all of these examples involve randomness.
objectives of this study in color and form.
random examples Simple color randomness is not very artful, but it provides a starting point and a comparison.
noise examples Noise is a subject with a large literature in physics and engineering. There are standard ways of describing it mathematically. Noise is not purely random but provides colors which are correlated smoothly from one location to another. There are many ways of adjusting the properies of these smooth two-dimensional functions.
random walk examples This also has a large literature. It provides a model for a number of natural processes such as diffusion. The colors resulting from such a process are correlated from one square to another. Random walk in color space appears to be novel.
flicker noise examples Flicker or "1/f" noise is quite common in nature and now finds a use in art.
images Finished images made by the techniques presented.
Vector graphics is used, so that each colored region is "hard edged".
Squares and rectangles are used so that all of the patterns can be compared without the distractions of different shapes. In practice these techniques would be applied to a variety of shapes, the choice of shape being the most challenging part of the development.
