% function color_rgb = color_choice(choice)
%
% Function used to create output color based of the specified index, useful
% for plotting multiple overlaid plots using the "hold on" command
%
% Inputs:
%   choice: Positive integer index specifying the color RGB values to be 
%       output. If the choice valuse is greater than the number of colors
%       in the list, the plot color will wrap around back to the first in
%       the list in a modulo fashion.
% Outputs:
%   color_rgb: Array of RGB values for the specified color
