Background Color

Colors are displayed in Fred's Fractal Viewer by mapping the Mandelbrot Escape Count to indexes into the 256 color palette. The indexes into the palette range from 0 to 255.

• The 0 index is reserved for the background color which is used to paint the pixels with an Escape Count >= MaxIterations.
• The default mapping for pixels with an associated Escape Count < MaxIterations: palette color index = (Escape Count % 255) + 1 .

Use the Background Color dialog to set the current background color.
