color_change(col,my_view,x,y,Zvalues,x_view,y_view,maxIter,myLight)

function color_change(col,my_view,x,y,Zvalues,x_view,y_view,maxIter,myLight)
% This function does the coloring and light effect for the Mandel120
% program. It applies several standard a few custom colormaps to fit the
% mandelbrot set.

% Example
% color_change(15,3,x,y,Zvalues,29,72,50,3);
% where x,y,Zvalues are the coordinates that are generated by dummy2.m
% the dummy2.m returns x,y,Zvalues to the worksapce is launched from the
% command line.
