Adjusting the palette is done in the palette editor. It allows you to adjust the colors, to choose the type of interpolation and to choose the color model. Several preset palettes are provided with ChaosPro, so you should already have some coloring schemes for your fractals. The palette editor looks as follows:
As you can see, there are three display fields, one for each color component (red, green, blue). By looking at a color component you can easily identify the different control points and the interpolation line.
In order to have a common understanding, let's explain and define what a control point actually is:
What can one do with the color components displayed above?
To the left and right side of each displayfield there is a so called "color simulator": It shows you what would happen if you would move the current control point up or down.
Below the displayfields there is the offset slider: This slider allows you to displace the palette.
And below the offset slider at the left edge of the palette editor there is the color selector: It displays the current color. By clicking onto the filled circle another window will open which allows you to choose a color using the HSL color wheel.
The items beneath the color selector let you view or manually adjust the color values.
And the last item in the palette editor is the Smooth checkbox. If it is not checked, then the control points are interpolated using linear interpolation. Otherwise the control points are interpolated using a limited cubic spline (i.e. a smooth curve).
