Figure 15.278: Color tab options
This tab contains options for fractal color setting.
Color number This slider and its input boxes allow you to set the number of colors for the fractal, between 2 and 8192.
A palette of these colors is displayed at the bottom of the tab. Actually, that’s a gradient between colors in fractal:
you can change colors with ‘Color intensity ’ and ‘Color function ’ options. Fractal colors don’t depend on colors of
the original image (you can use a white image for fractals as well).

Use loglog-smoothing If this option is checked, the band effect is smoothed.

Color density These three sliders and their inputboxes let you set the color intensity in the three Red, Green and Blue
color channels. Values vary from 0.0 to 1.0.
Color function For the Red, Green and Blue color channels, you can select how color will be treated:
• Sinus: Color variations will be modulated according to the sinus function.
• Cosinus: Color densities will vary according to cosinus function.
• None: Color densities will vary linearly.
• Inversion: if you check this option, function values will be inverted.
Color Mode These options allow you to set where color values must be taken from.
• As specified above: Color values will be taken from the Color density options.
