In the early days of fractals computers were only able to create black and white images. Fractals were quite boring from an artists point of view:
Well, the images were fascinating, especially because they seemed to have an infinite amount of detail.
Computer systems needed days to weeks just to calculate a single image!
And then this image was only black and white…
But then computers went better and better, they were more powerful, had better graphics capabilities, and then programs were able to calculate colorful fractals.
Nowadays the colors assigned to a fractal play a very important role in making a fractal beaultiful.
One of the key features of modern fractal generators is to give the user as much control over the colors used to draw the fractal as possible.
A fractal can be boring if the colors are not well chosen. Colors can enhance the details, they can emphasize structures which otherwise would be too weak to get noticed.
In ChaosPro you use palettes to color a fractal: A palette is a set of colors which get used by the fractal. By adjusting the palette you change the colors used by the fractal. Each fractal has its own palette.
In ChaosPro a palette consists of upto about 250 different colors (normally much fewer colors), which then are interpolated and so form a “path”, the so called color gradient:
Well, the sum of all colors is called the “color space”. It’s a three dimensional object, normally a cube as seen at the left side (at least if the RGB color model is used).
Suppose you place some points anywhere inside that cube and then draw a line through your points. Then this is what happens in ChaosPro: You define some colors, and ChaosPro uses your colors and interpolates them to form a smooth range of colors, a long, wicked line inside the cube…
