+Coloring of a fractal can be derived from the information that is available throughout the iteration process.
+The simplest is coloring a point based on the original location of the point.
+Next is coloring a point based on the final location of the point at termination of the iteration process.
+However we can derive more complex algorithms based on data obtained during the iteration process (e.g orbit trap algorithms and auxColor algorithms).
+All of the above can be used together to form even more complicated algorithms (e.g Mandelbox coloring options below).

 \subsubsection{Color by numbers}\label{materials-color by numbers}
 
+Color by numbers is a mathematical approach (which also helps with fractal calculation diagnostics).
+if the Color Speed is at default 1.0, then a calculated colorValue of 2.5 will assign the color at a distance of 2.5 along the palette gradient.
